Description

Technical Field

[0001] This application relates to the field of optical device technology, and in particular to an optical component and an optical module. Background Technology

[0002] With the development of society, people's requirements for bandwidth are increasing. Under the condition that the core component speed remains unchanged, the bandwidth of the system can be improved by combining multiple optical wavelengths of different wavelengths into one optical wavelength. The process of combining multiple optical wavelengths of different wavelengths into one optical wavelength requires an optical multiplexer (OMUX).

[0003] In the existing technology, optical multiplexing schemes based on thin-film filters are the mainstream multiplexing schemes, which are widely used in various optical devices that require wavelength division and multiplexing. Figure 1 This is a schematic diagram of an integrated optical module. (Example) Figure 1 As shown, the integrated optical module includes a light source 1, a collimating lens 2, a filter 3, an optical fiber adapter 4, a four-sided parallel glass substrate 5, and a converging lens 6. A collimating lens 2 is disposed on one side of each light source 1 to ensure that the light emitted from the light source 1 is paralleled after passing through the collimating lens 2. The four-sided parallel glass substrate 5 is disposed on the side of the collimating lens 2 away from the light source 1, and the filter 3 is disposed on the side of the four-sided parallel glass substrate 5 closest to the collimating lens 1. A high-reflection film is disposed on the side of the four-sided parallel glass substrate 5 away from the collimating lens 2. Light emitted from different light sources 1 undergoes multiple reflections within the four-sided parallel glass substrate 5 and is then combined into a single beam, which is then converged by the converging lens 6 before entering the optical adapter 4. This light combining method based on a thin-film filter can significantly improve the system bandwidth.

[0004] However, the wave combining scheme based on thin-film filters first requires fabricating an optical wave combiner from the filter and the glass block, and then placing the entire optical wave combiner into the optical device for use. Moreover, during use, collimated light needs to be input, and the output collimated light also needs to be converged by a converging lens before entering the optical adapter, making its structure complex and costly. Summary of the Invention

[0005] This application provides an optical component and an optical module. The optical component can combine multiple light waves of different wavelengths into a single light wave, and its structure is simple and low cost.

[0006] The first aspect of this application provides an optical component, which includes a plurality of light-emitting elements, each emitting incident light of different wavelengths; a plurality of converging lenses, each disposed opposite to the light-emitting elements, wherein the incident end of the converging lens is opposite to the light-emitting surface of the light-emitting element, and the converging lens is used to convert the diverging incident light into converged outgoing light; and an optical fiber adapter, disposed opposite to the converging lenses, with the optical fiber adapter located on the side of the converging lenses away from the light-emitting elements; the incident end face of the optical fiber adapter has a converging position, and outgoing light at different angles enters the optical fiber adapter at the converging position in a converged manner, wherein the angle between the optical axis of the light rays entering the optical fiber adapter at the converging position and the central axis of the optical fiber adapter is less than or equal to a preset angle.

[0007] The optical component of this application embodiment, by setting a converging lens on the emitting surface of the light-emitting element, can convert the divergent incident light emitted by the light-emitting element into converged outgoing light, and then directly couple light of different wavelengths into the fiber optic adapter. Since the angle between the optical axis of the light entering the fiber optic adapter at the converging position and the central axis of the fiber optic adapter is designed to be less than or equal to a preset angle, the optical power of the light entering the fiber optic adapter is relatively high within this preset angle range. Therefore, this ensures high coupling efficiency of the optical wave combiner, meeting the optical power requirements of the optical device. Compared to the existing thin-film filter wave combiner scheme, which requires fabricating an OMUX (Optical Multi-Mesh Array) using a filter and glass block, and then placing the OMUX as a whole into the optical device, and requiring collimated light input and converged output collimated light through a converging lens before entering the fiber optic adapter, the optical component in this application embodiment has a simpler structure, resulting in lower costs.

[0008] In one alternative implementation, the preset angle is 10°.

[0009] By setting the preset angle to 10°, the angle between the optical axis of the light entering the fiber optic adapter at the convergence position and the central axis of the fiber optic adapter is less than or equal to 10°. Since this preset angle is small, the optical power loss of the laser is small. Therefore, this can ensure that the coupling efficiency of the light entering the fiber optic adapter at the convergence position is high, so as to adapt to optical devices with high coupling efficiency requirements.

[0010] In one optional implementation, the plurality of light-emitting elements includes at least one first light-emitting element; wherein the emitted light corresponding to the first light-emitting element is a first emitted light; the angle between the optical axis of the first emitted light and the central axis of the fiber optic adapter is less than or equal to a preset angle; and the first emitted light enters the fiber optic adapter at the converging position.

[0011] The optical component provided in this application designes the angle between the optical axis of the first emitted light corresponding to the first light-emitting element and the central axis of the fiber optic adapter to be less than or equal to a preset angle. This ensures that the first emitted light is directly incident into the fiber optic adapter at the converging position, guaranteeing that the angle between the optical axis of the light entering the fiber optic adapter at the converging position and the central axis of the fiber optic adapter is less than or equal to the preset angle. Therefore, the first emitted light after passing through the converging lens can be directly coupled into the fiber optic adapter. This not only greatly simplifies the structure of the optical device and reduces costs but also ensures high coupling efficiency.

[0012] In one optional implementation, the plurality of light-emitting elements further includes at least one second light-emitting element; wherein the emitted light corresponding to the second light-emitting element is a second emitted light; the angle between the optical axis of the second emitted light and the central axis of the fiber optic adapter is greater than the preset angle; and the second emitted light enters the fiber optic adapter at the converging position after reflection.

[0013] The optical component provided in this application embodiment, by setting a first light-emitting element and a second light-emitting element, restricts the angle between the optical axis of the first emitted light and the central axis of the fiber optic adapter to within a preset angle, and restricts the angle between the optical axis of the second emitted light corresponding to the second light-emitting element and the central axis of the fiber optic adapter to outside the preset angle, and then reflects the second emitted light and injects it into the fiber optic adapter at the converging position, can increase the number of coupled light waves to achieve coupling of more light waves of different wavelengths. In addition, since the angle between the optical axis of the light entering the fiber optic adapter at the converging position and the central axis of the fiber optic adapter is less than or equal to the preset angle, although the incident angle of the second emitted light corresponding to the second light-emitting element is relatively large compared to the fiber optic adapter, after reflection it also becomes light with an incident angle less than or equal to the preset angle, so it will not affect the optical power of the light entering the fiber optic adapter. Therefore, while increasing the number of coupled light waves, it also ensures the optical coupling efficiency.

[0014] In one optional implementation, at least one set of reflective components is further included, the reflective components being disposed between the converging lens and the fiber optic adapter; each set of the reflective components is used to reflect the second emitted light corresponding to a second light-emitting element to the converging position; wherein, the second emitted light is reflected by the reflective components to obtain reflected light, the optical path of the reflected light extends to the converging position, and the angle between the optical axis of the reflected light entering the fiber optic adapter at the converging position and the central axis of the fiber optic adapter is less than or equal to the preset angle.

[0015] The optical component provided in this application embodiment, by incorporating a reflective component, allows the second emitted light to change direction after reflection and ultimately enter the fiber optic adapter at the converging position. This ensures that the angle between the optical axis of the reflected light entering the fiber optic adapter at the converging position and the central axis of the fiber optic adapter is less than or equal to a preset angle. Therefore, by incorporating the reflective component, light emitted from more light-emitting elements with different incident angles can be coupled into the fiber optic adapter, and the coupling efficiency entering the fiber optic adapter can be guaranteed to be at a high level.

[0016] In one optional implementation, the second emitted light is reflected at least twice by the reflecting component and then enters the fiber optic adapter at the converging position; the reflected light includes a first reflected light and a second reflected light; the second emitted light is reflected for the first time by the reflecting component to obtain the first reflected light; the first reflected light is reflected for the second time by the reflecting component to obtain the second reflected light; the optical path of the second reflected light extends to the converging position and enters the fiber optic adapter at the converging position, wherein the angle between the optical axis of the second reflected light and the central axis of the fiber optic adapter is less than or equal to the preset angle.

[0017] In one alternative implementation, a portion of the structure of each group of the reflective components is located in the optical path of the second emitted light corresponding to one of the second light-emitting elements, and a portion of the structure of each group of the reflective components is located in the optical path of the first emitted light corresponding to one of the first light-emitting elements.

[0018] The optical component provided in this application embodiment, by setting a portion of the structure of each set of reflective components in the optical path of the second emitted light corresponding to one of the second light-emitting elements, can perform a first reflection of the second emitted light to obtain a first reflected light; by setting a portion of the structure of each set of reflective components in the optical path of the first emitted light corresponding to one of the first light-emitting elements, the first reflected light can be reflected a second time at a position close to or within the optical path of the first emitted light, so that the optical path of the second reflected light is oriented towards the incident end of the fiber optic adapter, thereby ensuring that the second emitted light corresponding to the second light-emitting element can finally enter the fiber optic adapter at a small angle at the convergence position, thereby ensuring a high coupling efficiency of the second reflected light (i.e., the second emitted light) in the fiber optic adapter, thus realizing the coupling of multiple light waves of different wavelengths and ensuring a high coupling efficiency of the coupled waves.

[0019] In one optional implementation, each set of the reflective components includes a mirror and a filter; wherein the filter has a reflective surface; the mirror is disposed in the optical path of the second emitted light corresponding to a second light-emitting element, and the second emitted light is reflected by the mirror to obtain the first reflected light; the filter is located in the optical path of the first reflected light; the reflective surface of the filter and the mirror are disposed opposite to each other, and the reflective surface of the filter faces the fiber optic adapter; the first reflected light is reflected by the reflective surface of the filter to obtain the second reflected light.

[0020] The optical component provided in this application, by designing the reflective component as a structure including a reflector and a filter, allows the second emitted light to enter the fiber optic adapter at the converging position after two reflections, thereby completing the coupling of multiple light waves. By placing the reflector in the optical path of the second emitted light corresponding to a second light-emitting element, all of the second emitted light is reflected onto the filter, thus ensuring the optical power of the second emitted light and avoiding optical loss during reflection. By setting a reflective surface on the filter, the filter can have a reflective function, allowing the first reflected light, after being reflected by the reflector, to be reflected a second time to obtain the second reflected light. After the second emitted light undergoes two reflections, the direction of the optical path changes, from an angle greater than a preset angle with the central axis of the fiber optic adapter to an angle less than or equal to a preset angle. In other words, after two reflections, the angle between the optical axis of the second emitted light entering the fiber optic adapter from the converging position and the central axis of the fiber optic adapter becomes less than or equal to a preset angle. This allows more light waves entering at different angles to be coupled into the fiber optic adapter, with higher coupling efficiency, thus accommodating a wider range of optical devices.

[0021] In one alternative implementation, the filter is located between the reflector and the converging lens corresponding to one of the first light-emitting elements; at least a portion of the filter is located in the optical path of the first emitted light corresponding to one of the first light-emitting elements; the filter is used to transmit the first emitted light corresponding to one of the first light-emitting elements through the reflective surface, so that the first emitted light converges at the converging position.

[0022] The optical component provided in this application embodiment receives first reflected light by placing a filter between a reflector and a converging lens corresponding to one of the first light-emitting elements. Since the angle between the optical axis of the first emitted light corresponding to the first light-emitting element and the central axis of the fiber optic adapter is less than or equal to a preset angle, and the angle between the optical axis of the second emitted light corresponding to the second light-emitting element and the central axis of the fiber optic adapter is greater than a preset angle, the first light-emitting element will be closer to the central axis of the fiber optic adapter relative to the second light-emitting element when the converging position remains unchanged; that is, the first light-emitting element is located inside the second light-emitting element. By placing at least a portion of the filter in the optical path of the first emitted light, the filter is closer to the optical path of the first emitted light, making it easier to reflect the first reflected light in a direction closer to the first emitted light, thereby reducing the angle between the optical axis of the second reflected light and the central axis of the fiber optic adapter, and thus improving coupling efficiency.

[0023] In one optional implementation, a selective light-transmitting film is provided on the side of the filter closest to the fiber optic adapter, and the selective light-transmitting film serves as the reflective surface; the selective light-transmitting film is used to transmit the first emitted light and also to reflect the first reflected light.

[0024] The optical component provided in this application embodiment allows light of a specific wavelength to pass through the filter by setting a selectively transparent film on the side of the filter near the fiber optic adapter. Light waves that cannot pass through are reflected on the surface of the selectively transparent film. This ensures that even if part or all of the filter is located in the optical path of the first emitted light, the optical power of the first emitted light entering the fiber optic adapter will not be affected, i.e., the coupling efficiency of the first emitted light will not be affected. In other words, by setting a selectively transparent film on the filter, the coupling efficiency of the first emitted light corresponding to the first light-emitting element can be guaranteed, and the coupling efficiency of the second emitted light corresponding to the second light-emitting element can be reflected to the converging position, thus guaranteeing the coupling efficiency of the light corresponding to the second light-emitting element.

[0025] In one alternative implementation, each set of the reflective components contains one reflector and one filter.

[0026] The optical component provided in this application simplifies the optical component by designing the reflective component into a structure including a reflector and a filter, thereby reducing the cost of the optical component. In addition, by setting a reflector and a filter, the second outgoing light only needs to undergo two reflections to ensure that the angle between the optical axis of the light entering the fiber optic adapter at the final converging position and the central axis of the fiber optic adapter is less than or equal to a preset angle. The fewer reflections reduce light loss and ensure that the optical power of the light wave entering the incident end of the fiber optic adapter can meet the needs of the optical device.

[0027] In one optional implementation, the number of reflectors in each group of reflective components is multiple and an odd number; wherein the multiple reflectors are arranged opposite each other, and the lines connecting the multiple reflectors are in a zigzag pattern; and the number of filters is one.

[0028] The optical component provided in this application embodiment, by designing the reflective component to include multiple reflectors, with the lines connecting the multiple reflectors forming a zigzag shape, allows the second emitted light to reach the filter after multiple reflections. This enables light waves with a larger incident angle relative to the fiber optic adapter to be coupled into the fiber optic adapter with a higher coupling rate. Furthermore, by using multiple reflectors, the optical path of the second emitted light can be altered multiple times before entering the fiber optic adapter, thus increasing the design flexibility of the optical component.

[0029] In one alternative implementation, the number of the reflective components is the same as the number of the second light-emitting elements.

[0030] The optical components provided in this application embodiment, by designing the number of reflective components and second light-emitting elements to be the same, can ensure that the second emitted light corresponding to each second light-emitting element is coupled into the fiber optic adapter with a high coupling rate. This ensures that the light waves of each wavelength coupled into the fiber optic adapter meet the usage requirements of the optical device.

[0031] In one alternative implementation, the number of the first light-emitting elements is multiple; wherein the multiple first light-emitting elements are symmetrically arranged about the central axis of the fiber optic adapter.

[0032] The optical component provided in this application embodiment achieves the coupling of light waves of different wavelengths into the fiber optic adapter by designing multiple first light-emitting elements. Furthermore, since the angle between the optical axis of the first emitted light corresponding to the first light-emitting element and the central axis of the fiber optic adapter is less than or equal to a preset angle, only a converging lens needs to be placed on the emitting surface of the first light-emitting element to couple the first emitted light into the fiber optic adapter. This simplifies the structure of the optical component and further reduces costs. Additionally, by symmetrically arranging multiple first light-emitting elements with the normal line passing through the convergence position on the end face of the fiber optic adapter's incident end as the axis of symmetry, the industrial aesthetics of the optical component are enhanced.

[0033] In one optional implementation, there are multiple first light-emitting elements and multiple second light-emitting elements; wherein, the multiple second light-emitting elements are symmetrically arranged with the central axis of the fiber optic adapter as the axis of symmetry; and the multiple first light-emitting elements are symmetrically arranged with the central axis of the fiber optic adapter as the axis of symmetry.

[0034] A second aspect of this application provides an optical module, including the optical components of the first aspect.

[0035] The optical module in this embodiment of the application can combine multiple light waves of different wavelengths into one light wave by setting the optical components of the first aspect. Since the optical components have a simple structure and low cost, the structure of the optical module is also relatively simple and the cost is correspondingly lower. Attached Figure Description

[0050] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0051] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and its other forms, such as the third-person singular "comprises" and the present participle "comprising," are interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiments," "example," or "some examples" are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.

[0052] Furthermore, in this application, directional terms such as "front" and "rear" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0053] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0054] With the development of society, people's requirements for bandwidth are increasing. In existing technologies, the method of combining multiple wavelengths of light into one light is usually adopted to improve the bandwidth of the system in order to meet people's needs.

[0055] In existing technologies, optical multiplexers (OMUX) with thin-film filters are typically used to combine multiple wavelengths of light into a single beam. Figure 1 This is a schematic diagram of an integrated optical module. (Example) Figure 1 As shown, the existing integrated optical module includes a light source 1, a collimating lens 2, a filter 3, an optical fiber adapter 4, a four-sided parallel glass substrate 5, and a converging lens 6. The filter 3 is positioned on the side of the glass substrate 5 closest to the light source 1. A collimating lens 2 is positioned on the emitting surface of each light source 1, allowing the light emitted from the light source 1 to be collimated. By using multiple light sources 1 and collimating lenses 2, a set of collimated parallel beams can be generated. This collimated parallel beam passes through the filter 3 and enters the glass substrate 5, undergoing multiple reflections before converging into a single beam. This beam then passes through a converging lens 6 and enters the optical adapter 4. In the aforementioned integrated optical module, the filter 3 and the glass substrate 5 constitute an optical combiner. While using this combiner method can significantly improve the system bandwidth...

[0056] but, Figure 1The integrated optical module in the present technology has a relatively complex structure. It requires fabricating an optical combiner from the filter 3 and the glass substrate 5, then placing the entire optical combiner into the optical device for use. During operation, collimated light needs to be input, and the output collimated light needs to be focused by a converging lens before entering the optical adapter. This complexity increases the cost of the integrated optical module. Therefore, the existing integrated optical module is not conducive to cost reduction. However, due to the widespread application of optical devices, especially in the field of domain controllers (DCs), there is an even stronger demand for cost-effectiveness in optical devices.

[0057] To address the issue of high cost in existing optical wave combining systems, this application provides an optical component and optical module that are simple in structure and low in cost.

[0058] It should be noted that due to advancements in laser technology, the output power of current lasers far exceeds the system specifications. In other words, the output power of existing lasers exceeds the power requirements of current optical devices. This can be understood as existing lasers having a significant margin of safety while still meeting the needs of optical devices. In other words, utilizing only a portion of the laser's output power is sufficient to meet the requirements of existing optical devices. Therefore, we can reduce the complexity of the multiplexing system and achieve lower costs by sacrificing some coupling efficiency (i.e., sacrificing some of the laser's power).

[0059] The specific structure of the optical component 100 in the embodiments of this application will be described in detail below.

[0060] Figure 2 This is a schematic diagram of the structure of an optical component 100 provided in one embodiment of this application. Figure 2 As shown, this application embodiment provides an optical component 100, which may include two light-emitting elements 110, two converging lenses 120, and a fiber optic adapter 140. Each light-emitting element 110 may have a converging lens 120 disposed on one side, and the fiber optic adapter 140 is disposed on the side of the converging lens 120 away from the light-emitting element 110. The emitting ends of both converging lenses 120 face the fiber optic adapter 140. Of course, in some embodiments, the number of light-emitting elements 110 and converging lenses 120 may be three, four, five, or even more; the number of light-emitting elements 110 and converging lenses 120 is not limited in this embodiment.

[0061] See Figure 2As can be seen from the light path, the incident end of the converging lens 120 is opposite to the light-emitting surface 113 of the light-emitting element, so that the light emitted by the light-emitting element 110 can enter the converging lens 120. The two light-emitting elements 110 are used to emit incident light 114 with different wavelengths, and the converging lens 120 is used to convert the diverging incident light 114 into converged outgoing light. The fiber optic adapter 140 is positioned opposite the converging lens 120, located on the side of the converging lens 120 away from the light-emitting element 110. A converging position 150 is provided on the incident end 141 of the fiber optic adapter. Outgoing light 115 at different angles converges and enters the fiber optic adapter 140 at the converging position 150. The angle between the optical axis of the light rays entering the fiber optic adapter 140 at the converging position 150 and the central axis 143 of the fiber optic adapter is less than or equal to a preset angle.

[0062] It should be noted that the dashed line in the middle of the light rays in the diagram represents the optical axis.

[0063] The optical component 100 of this application embodiment converts the divergent incident light 114 emitted by the light-emitting element 110 into a converged outgoing light 115 by setting a converging lens 120 on the light-emitting surface 113 of the light-emitting element. This allows light of different wavelengths to be directly coupled into the fiber optic adapter 140. Since the angle between the optical axis of the light entering the fiber optic adapter 140 at the converging position 150 and the central axis 143 of the fiber optic adapter is designed to be less than or equal to a preset angle, the optical power of the light entering the fiber optic adapter 140 is relatively high within this preset angle range. Therefore, this ensures high optical coupling efficiency and meets the optical power requirements of the optical device. This direct optical coupling solution, compared to the existing thin-film filter 132 multiplexing solution, requires the filter 132 and a glass block optical multiplexer to be fabricated, and then the entire optical multiplexer is placed in the optical device for use. Furthermore, during use, collimated light needs to be input, and the output collimated light needs to be converged by the converging lens 120 before entering the optical adapter. The optical component 100 in this embodiment has a simpler structure, thereby achieving a lower cost.

[0064] In this embodiment of the application, for ease of description, the light emitted by the light-emitting element 110 is referred to as the incident light 114, and the light emitted after passing through the converging lens 120 is referred to as the outgoing light 115.

[0065] It should be noted that different optical devices require different optical power, and the amount of optical power input to an optical device can be understood as the amount of light entering the fiber optic adapter 140. It can be understood that the optical power of light incident perpendicularly into the fiber optic adapter 140 is the highest, while the optical power of light incident at a certain angle into the fiber optic adapter 140 decreases, thus reducing the coupling efficiency. Furthermore, the larger the angle of incidence relative to the fiber optic adapter, the greater the reduction in optical power, and the lower the corresponding coupling efficiency. Therefore, by controlling the incident angle of light on the fiber optic adapter 140, the optical power entering the optical device can be controlled, thereby controlling the coupling efficiency.

[0066] It should be noted that the incident angle of the emitted light 115 on the fiber optic adapter 140 is the angle between the optical axis of the emitted light 115 and the central axis 143 of the fiber optic adapter. Since the optical axes of the emitted light 115 and the incident light 114 are in the same direction, the incident angle of the light-emitting element 110 on the fiber optic adapter 140 is the angle between the optical axis of the emitted light 115 and the central axis 143 of the fiber optic adapter.

[0067] In this embodiment, the optical power entering the optical device can be controlled by controlling the incident angle of the emitted light 115 of the light-emitting element 110 on the optical fiber adapter 140, thereby controlling the coupling efficiency.

[0068] In this embodiment, the light-emitting element 110 can be a laser. The output power of existing lasers already far exceeds the system specifications of optical devices. Therefore, it is not necessary to couple all the light emitted by the laser into the fiber optic adapter 140 to meet the requirements of the optical device. In other words, as long as a portion of the laser light is coupled into the fiber optic adapter 140, the requirements of the optical device can be met. Therefore, the laser can be directed into the fiber optic adapter 140 at a certain angle. Although this sacrifices some coupling efficiency, it still meets the requirements of the optical device. However, this greatly simplifies the structure of the optical component 100, thereby significantly reducing costs.

[0069] Therefore, in this embodiment, as Figure 2As shown, the angle between the optical axis of the emitted light 115 of the light-emitting element 110 and the central axis 143 of the fiber optic adapter can be set to be greater than 0. For example, the angle α between the optical axis of the emitted light 115 and the central axis 143 of the fiber optic adapter can be set to be greater than 0 and less than or equal to a preset angle, where the preset angle can be 10°. That is, the angle α between the optical axis of the emitted light 115 of the light-emitting element 110 and the central axis 143 of the fiber optic adapter is less than or equal to 10°. This reduces the coupling efficiency of the emitted light 115 somewhat, but it fully meets the needs of most optical devices. At the same time, it simplifies the structure of the optical assembly 100, thereby greatly reducing the cost of the optical assembly 100.

[0070] Of course, in other embodiments, the preset angle can also be other values, such as 11°, 12° or larger. In the embodiments of this application, the value of this preset angle is not limited and can be set according to the needs of the optical device.

[0071] In this embodiment, as Figure 2 As shown, the outgoing light 115 enters the fiber optic adapter 140 directly from the converging position 150. In other words, the outgoing light 115 is the light that enters the fiber optic adapter 140 from the converging position 150.

[0072] It should be noted that fiber optic adapter 140 includes fiber optic cable 142, such as... Figure 2 As shown, the central axis of optical fiber 142 and the central axis 143 of the optical fiber adapter are on the same straight line. The light waves emitted by the multiple light-emitting elements 110 are coupled and enter the optical fiber 142 in the optical fiber adapter 140.

[0073] The above-described technical solution, which directly couples the emitted light 115 of the light-emitting element 110 into the fiber optic adapter 140, requires that the incident angle of the emitted light 115 of the light-emitting element 110 on the fiber optic adapter 140 be less than or equal to a preset angle. Of course, in some embodiments, the incident angle of the emitted light 115 of some light-emitting elements 110 on the fiber optic adapter 140 may be greater than the preset angle. For example... Figure 3 As shown, in this embodiment, the light-emitting element 110 includes a first light-emitting element 111 and a second light-emitting element 112.

[0074] Wherein, the emitted light 115 corresponding to the first light-emitting element 111 is the first emitted light 1111, and the angle between the optical axis of the first emitted light 1111 and the central axis 143 of the fiber optic adapter is set to be less than or equal to a preset angle; the emitted light 115 corresponding to the second light-emitting element 112 is the second emitted light 1121, and the angle θ between the optical axis of the second emitted light 1121 and the central axis 143 of the fiber optic adapter is set to be greater than a preset angle.

[0075] In this embodiment, the first emitted light 1111 can be directly coupled into the fiber optic adapter, while the second emitted light 1121 can be reflected to change its initial optical path, causing the light emitted by the second light-emitting element 112 to ultimately enter the fiber optic adapter 140 at the convergence position 150 at an angle smaller than a preset angle. This ensures coupling efficiency and allows for the adaptation to more optical devices.

[0076] like Figure 3 As shown, the optical component 100 in this embodiment includes four light-emitting elements 110, four converging lenses 120, two sets of reflective components 130, and a fiber optic adapter 140. The four light-emitting elements 110 include two first light-emitting elements 111 and two second light-emitting elements 112. A converging lens 120 is disposed on the light-emitting surface 113 of each first light-emitting element 111, and a converging lens 120 is disposed on the light-emitting surface 113 of each second light-emitting element 112. A fiber optic adapter 140 is disposed on the side of the converging lens 120 away from the second light-emitting elements 112. A set of reflective components 130 is disposed between the converging lens 120 and the fiber optic adapter 140 corresponding to each second light-emitting element 112. Each set of reflective components 130 is used to reflect the second emitted light 1121 corresponding to one of the second light-emitting elements 112 to a converging position 150, and then into the fiber optic adapter 140 at the converging position 150.

[0077] In this embodiment, the second emitted light 1121 is reflected at least twice by the reflecting component 130 and then enters the fiber optic adapter 140 at the converging position 150. The second emitted light 1121 is reflected by the reflecting component 130 to obtain reflected light. The reflected light includes a first reflected light 1122 and a second reflected light 1123; wherein, the second emitted light 1121 is reflected for the first time by the reflecting component 130 to obtain the first reflected light 1122; the first reflected light 1122 is reflected for the second time by the reflecting component 130 to obtain the second reflected light 1123; the optical path of the second reflected light 1123 extends to the converging position 150 and enters the fiber optic adapter 140 at the converging position 150, and the angle θ1 between the optical axis of the second reflected light 1123 and the central axis 143 of the fiber optic adapter is less than or equal to a preset angle.

[0078] In this embodiment, the first emitted light 1111 and the second reflected light 1123 are both light rays that enter the fiber optic adapter 140 at the converging position 150, and the angle between the light rays entering the fiber optic adapter 140 at the converging position 150 and the central axis 143 of the fiber optic adapter is less than or equal to a preset angle.

[0079] The optical component 100 provided in this embodiment of the application, by setting a reflection component 130, allows the second emitted light 1121 to change direction after reflection and finally enter the fiber optic adapter 140 at the converging position 150. This ensures that the angle θ1 between the optical axis of the second emitted light 1121 that finally enters the fiber optic adapter 140 at the converging position 150 after reflection and the central axis 143 of the fiber optic adapter is less than or equal to a preset angle. Therefore, by setting the reflection component 130, light emitted from more light-emitting elements 110 with different incident angles can be coupled into the fiber optic adapter 140, and the coupling efficiency entering the fiber optic adapter 140 can be guaranteed to be at a high level.

[0080] It should be noted that, in some special cases, the angle α between the optical axis of the first emitted light 1111 and the central axis 143 of the fiber optic adapter can be the same as the angle θ1 between the optical axis of the second light-emitting element 112 and the central axis 143 of the fiber optic adapter at the final convergence position 150. Figure 4 As shown. However, the values ​​of α and θ1 include, but are not limited to, being the same, as long as they are both less than or equal to the preset angle, they fall within the scope of protection of the embodiments of this application.

[0081] See also Figure 3 As shown, in this embodiment, each set of reflective components 130 may include a reflector 131 and a filter 132; wherein, the reflector 131 is disposed in the optical path of the second emitted light 1121 corresponding to the second light-emitting element 112; the filter 132 has a reflective surface 1321 and is located in the optical path of the first reflected light 1122; the reflective surface 1321 of the filter 132 and the reflector 131 are disposed opposite to each other, and the reflective surface 1321 of the filter 132 faces the fiber optic adapter 140; the second emitted light 1121 is reflected by the reflector 131 to obtain the first reflected light 1122; the first reflected light 1122 is reflected by the reflective surface 1321 of the filter 132 to obtain the second reflected light 1123.

[0082] The optical component 100 provided in this application embodiment, by designing the reflective component 130 to include a reflector 131 and a filter 132, allows the second emitted light 1121 to enter the fiber optic adapter 140 at the converging position 150 after two reflections, thereby completing the coupling of multiple light waves.

[0083] By placing the reflector 131 in the optical path of the second emitted light 1121 corresponding to the second light-emitting element 112, the second emitted light 1121 is completely reflected onto the filter 132, thereby ensuring the optical power of the second emitted light 1121 and avoiding light loss during the reflection process.

[0084] By setting a reflective surface 1321 on the filter 132, the filter 132 can have a reflective function. This allows the first reflected light 1122, which has been reflected by the reflector 131, to be reflected a second time to obtain the second reflected light 1123. After the second emitted light 1121 undergoes two reflections, the direction of the optical path changes. The angle θ between the second emitted light 1121 and the central axis 143 of the fiber optic adapter changes from a preset angle to an angle θ1 less than or equal to the preset angle. In other words, after the second emitted light 1121 undergoes two reflections, the angle between the optical axis and the central axis 143 of the fiber optic adapter becomes smaller. This ensures that more light waves entering at different angles are coupled into the fiber optic adapter 140, and the coupling efficiency is high, thus allowing it to accommodate more optical devices.

[0085] It should be noted that the structure of the reflective component 130 includes, but is not limited to, those mentioned above. Figure 3 The structure shown can be configured such that one component can reflect light waves, while the other can both reflect and transmit light waves. Furthermore, the placement of the reflective component 130 is not limited to... Figure 3 The placement of the reflective components 130 is as follows: a portion of the structure of each reflective component 130 is located on the optical path of the second emitted light 1121 corresponding to a second light-emitting element 112; a portion of the structure of each reflective component 130 is located on the optical path of the first reflected light 1122; the second reflected light 1123 can enter the fiber optic adapter 140 at the converging position 150; and the angle θ1 between the optical axis of the second reflected light 1123 and the central axis 143 of the fiber optic adapter is less than or equal to a preset angle. Specifically, this can be determined based on the angle of the reflective components 130 and the distance from the converging lens 120 to the fiber optic adapter 140. In this embodiment, the structure, placement, and angle of the reflective components 130 are not specifically limited.

[0086] In one alternative implementation, the filter 132 is located between the reflector 131 and the converging lens 120 corresponding to one of the first light-emitting elements 111; at least a portion of the filter 132 is located in the optical path of the first emitted light 1111 corresponding to one of the first light-emitting elements 111; the filter 132 is used to transmit the first emitted light 1111 corresponding to one of the first light-emitting elements 111 through the reflective surface 1321 so that the first emitted light 1111 converges at the converging position 150; in addition, the filter 132 is also used to reflect the first reflected light 1122 and then send it into the fiber optic adapter 140 at the converging position 150.

[0087] The optical assembly 100 provided in this application embodiment receives first reflected light 1122 by placing a filter 132 between a reflector 131 and a converging lens 120 corresponding to one of the first light-emitting elements 111. Since the angle α between the optical axis of the first emitted light 1111 corresponding to the first light-emitting element 111 and the central axis 143 of the fiber optic adapter is less than or equal to a preset angle, and the angle between the optical axis of the second emitted light 1121 corresponding to the second light-emitting element 112 and the central axis 143 of the fiber optic adapter is greater than the preset angle, the first light-emitting element 111 will be closer to the central axis 143 of the fiber optic adapter relative to the second light-emitting element 112 when the converging position 150 remains unchanged. That is, the first light-emitting element 111 is located inside the second light-emitting element 112. Furthermore, by placing at least a portion of the filter 132 in the optical path of the first emitted light 1111, the filter 132 is even closer to the central axis 143 of the fiber optic adapter, making the overall structure of the optical assembly 100 more compact. Therefore, it is easier to reflect the first reflected light 1122 towards the direction of the first emitted light 1111, thereby reducing the angle between the optical path of the second reflected light 1123 and the central axis 143 of the fiber optic adapter, and thus improving the coupling efficiency.

[0088] In one alternative implementation, a selective light-transmitting film is provided on the side of the filter 132 near the fiber optic adapter 140, and the selective light-transmitting film serves as a reflective surface 1321; the selective light-transmitting film is used to transmit the first emitted light 1111 and also to reflect the first reflected light 1122.

[0089] The optical component 100 provided in this application embodiment allows light of a specific wavelength to pass through the filter 132 near the fiber optic adapter 140 by providing a selective light-transmitting film. Light waves that cannot pass through are reflected from the surface of the selective light-transmitting film. Thus, even if part or all of the filter 132 is located in the optical path of the first emitted light 1111, the optical power of the first emitted light 1111 entering the fiber optic adapter 140 will not be affected, i.e., the coupling efficiency of the first emitted light 1111 will not be affected. In other words, by providing a selective light-transmitting film on the filter 132, the coupling efficiency of the light emitted by the first light-emitting element 111 can be guaranteed, and the second emitted light 1121 corresponding to the second light-emitting element 112 can be reflected to the converging position 150, ensuring the coupling efficiency of the light emitted by the second light-emitting element 112.

[0090] The optical component 100 provided in this application embodiment simplifies the structure of the optical component 100 by designing the reflective component 130 to include a reflector 131 and a filter 132, thereby reducing the cost of the optical component 100. In addition, by setting a reflector 131 and a filter 132, the second outgoing light 1121 only needs to undergo two reflections to ensure that the angle between the optical axis of the light entering the fiber optic adapter 150 at the converging position 150 and the central axis 143 of the fiber optic adapter is less than or equal to a preset angle. The fewer reflections reduce light loss and ensure that the optical power of the light wave entering the incident end 141 of the fiber optic adapter can meet the needs of the optical device.

[0091] Of course, in other embodiments, the number of reflectors 131 in each set of reflective components 130 can be multiple, and an odd number; wherein, the multiple reflectors 131 can be arranged relative to each other, and the lines connecting the multiple reflectors 131 are in a zigzag shape; the number of filters 132 is one. For example, the number of reflectors 131 can be three, and the number of filters 132 can be one, so that the second emitted light 1121 can reach the fiber optic adapter 140 after four reflections.

[0092] The optical component 100 provided in this application embodiment, by designing the reflective component 130 to include multiple reflectors 131, with the lines connecting the multiple reflectors 131 forming a zigzag shape, allows the second emitted light 1121 to reach the filter 132 after multiple reflections. This also allows light waves with a large angle to the central axis of the fiber optic adapter 140 to be coupled into the fiber optic adapter 140 with a high coupling rate. Furthermore, by setting multiple reflectors 131, the optical path of the second emitted light 1121 can be altered multiple times before entering the fiber optic adapter 140, requiring only a small angle change each time. This results in a smaller offset angle between the components of the reflective component 130, facilitating installation and increasing the design flexibility of the optical component 100.

[0093] In one alternative implementation, the number of reflective components 130 is the same as the number of second light-emitting elements 112. By designing the number of reflective components 130 and second light-emitting elements 112 to be the same, the second emitted light 1121 corresponding to each second light-emitting element 112 can be coupled into the fiber optic adapter 140 with a high coupling rate. This ensures that the light waves of each wavelength coupled into the fiber optic adapter 140 meet the requirements for use of the optical device.

[0094] In this embodiment of the application, there are two first light-emitting elements 111 and two light-emitting elements 112, and the first light-emitting elements 111 and the second light-emitting elements 112 are symmetrically arranged with the central axis of the fiber optic adapter 140 as the axis of symmetry.

[0095] By symmetrically arranging multiple first light-emitting elements 111 with the central axis of the fiber optic adapter 140 as the axis of symmetry, the coupling rate of light waves distributed on both sides of the fiber optic adapter 140 into the fiber optic adapter 140 can be the same, and the industrial aesthetics of the optical component 100 can be enhanced.

[0096] It should be noted that in this embodiment, the number of first light-emitting elements 111 is at least one, but can be two, three, or more. The number of second light-emitting elements 112 is at least one, but can be two, three, or more. The specific number of first light-emitting elements 111 and second light-emitting elements 112 is not specifically limited in this embodiment.

[0097] Of course, in some embodiments, the first light-emitting element 111 and the second light-emitting element 112 may also be arranged asymmetrically, such as... Figure 5 As shown, a first light-emitting element 111 and a second light-emitting element can both be placed on one side of the central axis of the fiber optic adapter 140, thus allowing two light sources of different wavelengths to be coupled into the fiber optic adapter 140. Of course, the specific positions of the first light-emitting element 111 and the second light-emitting element 112 can be set according to specific circumstances, and will not be elaborated here.

[0098] Furthermore, the above embodiments all include the first light-emitting element 111. In some embodiments, the first light-emitting element 111 may not be provided, such as... Figure 6 As shown, the optical assembly 100 includes two second light-emitting elements 112, two converging lenses 120, two sets of reflective components 130, and a fiber optic adapter 140. Each second light-emitting element 112 has a converging lens 120 disposed on its light-emitting surface 113; the fiber optic adapter 140 is disposed on the side of the converging lens 120 away from the second light-emitting element 112. A set of reflective components 130 is disposed between the converging lens 120 and the fiber optic adapter 140 corresponding to each second light-emitting element 112.

[0099] The reflective assembly 130 includes a reflector 131 and a filter 132. The reflector 131 is disposed in the optical path of the second emitted light 1121 corresponding to the second light-emitting element 112. The filter 132 has a reflective surface 1321 and is located in the optical path of the first reflected light 1122. The reflective surface 1321 of the filter 132 is disposed opposite to the reflector 131 and faces the fiber optic adapter 140. The second emitted light 1121 is reflected by the reflector 131 to obtain the first reflected light 1122. The first reflected light 1122 is reflected by the reflective surface 1321 of the filter 132 to obtain the second reflected light 1123. The optical path of the second reflected light 1123 extends to the converging position 150 and enters the fiber optic adapter 140 at the converging position 150.

[0100] In this embodiment, the angle θ between the optical axis of the second emitted light 1121 and the central axis 143 of the fiber optic adapter is greater than a preset angle. After being reflected by the reflection component 130, the angle θ1 between the optical axis of the second reflected light 1123 and the central axis 143 of the fiber optic adapter is less than or equal to the preset angle. Therefore, the coupling efficiency of the second emitted light 1121 is also at a high level.

[0101] The optical component 100 in this embodiment can couple light into the fiber optic adapter at an angle θ greater than a preset angle between the optical axis and the central axis 143 of the fiber optic adapter, with high coupling efficiency. Furthermore, the optical component 100 has a simple structure, which can significantly reduce costs.

[0102] In this embodiment, the fiber optic adapter 140 can be a multimode fiber optic adapter 140 or a single-mode fiber optic adapter 140 to meet the needs of different optical devices. Of course, the insertion loss of coupling can be reduced in the multimode fiber optic adapter 140. The specific type of fiber optic adapter 140 used is not further limited in this embodiment.

[0103] Furthermore, during the fabrication of the optical component 100 provided in this application embodiment, the light-emitting element 110, filter 132, and reflector 131 can be passively mounted directly into the optical device as patches. Then, the coupling of different light waves can be achieved by adjusting the position and angle of the converging lens 120. The fabrication process of this optical component 100 is simple and can also reduce costs.

[0104] In summary, the optical component 100 in this embodiment has the advantages of a short manufacturing process and simpler technology. In addition, the optical component 100 in this embodiment has a simple structure, which can solve the problem of high cost after the widespread application of optical devices.

[0105] A second aspect of this application provides an optical module in which an optical component 100 as described in any of the above embodiments is provided. By providing the optical component 100 as described in the above embodiments of this application, the optical module can couple multiple light waves of different wavelengths into a single light wave, and its simple structure can reduce costs.

For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components.
