Description

An optical component and optical module Technical Field

[0001] This invention belongs to the field of optical module technology, and particularly relates to an optical component and an optical module. Background Technology

[0002] With the rapid development of data centers, the transmission rate requirements of optical communication systems are constantly increasing. Under this trend, traditional multimode fiber can no longer meet the needs of high-speed transmission, and single-mode fiber is gradually being introduced into high-speed optical module transmission systems. In order to effectively reduce the cost of optical fiber, coarse wavelength division multiplexing (CWDM4) technology has been widely used.

[0003] In the field of data communication, the CWDM4 standard selects four wavelengths (1271-1331nm) close to the zero-dispersion point of G652 single-mode fiber for transmission. Currently, CWDM4 technology is mainly implemented in the following ways: AWG (Arrayed Waveguide Grating) scheme and ITL (Integrated Tunable Laser) scheme.

[0004] However, with the continuous improvement of optical communication transmission rates, signal quality and channel loss have become increasingly important, especially in long-distance transmission scenarios. For example, the AWG solution mentioned above suffers from high channel loss and poor signal quality in long-distance transmission scenarios; while the ITL solution has certain advantages over the AWG solution in long-distance transmission scenarios, the ITL solution has a lower chip yield and greater transmission loss.

[0005] In view of the above problems, there is an urgent need to develop a new type of optical component to solve these technical challenges and promote the advancement of optical communication technology. Summary of the Invention

[0009] In a preferred embodiment of the present invention, the second optical component is a steering prism and a lens; the light beam can be first turned by the steering prism and then converged and coupled to the lens at the receiving end, or the light beam can first pass through the lens and then through the steering prism to the receiving end.

[0010] In a preferred embodiment of the present invention, the steering prism is composed of a single prism or multiple segmented prisms, the number of which corresponds to the number of beams output by the wavelength division multiplexing component.

[0011] In a preferred embodiment of the present invention, the lens and the steering prism are either an integral structure or a separate structure.

[0012] In a preferred embodiment of the present invention, the first optical component includes a collimating focusing lens.

[0013] In a preferred embodiment of the present invention, the wavelength division multiplexing component is composed of a wavelength division multiplexer.

[0014] In a preferred embodiment of the present invention, the second optical component is a prism, or the wavelength division multiplexing component includes an incident collimating lens, a wavelength division multiplexer, and an exit lens.

[0015] In a preferred embodiment of the present invention, the optical fiber connector component includes an optical connector assembly, an optical fiber, and a pigtail.

[0016] In a preferred embodiment of the present invention, the light-adjusting plate assembly is disposed between the wavelength division multiplexing component and the second optical component. The light-adjusting plate assembly is arranged in a one-to-one correspondence with the filter disposed on the wavelength division multiplexing component. Each light-adjusting plate assembly includes a light-adjusting plate base and a light-adjusting plate for fine-tuning the angle of the signal light mounted on the light-adjusting plate base.

[0017] In a preferred embodiment of the present invention, the pigtail can be in various forms, such as a cylindrical fiber optic head, a single-core fiber array, a semi-circular or square shape, etc.

[0018] The present invention also discloses an optical module, characterized in that it includes a printed circuit board, on which an optical module receiver and an optical component are disposed, and the light beam is received by the optical module receiver after passing through the optical component.

[0019] In a preferred embodiment of the present invention, the light-adjusting plate assembly is disposed between the wavelength division multiplexer and the second optical component. The light-adjusting plate assembly is arranged in a one-to-one correspondence with the filter disposed on the wavelength division multiplexer.

[0023] The beneficial effects of this invention are as follows: The optical component provided by this invention has several significant advantages through optimized optical path structure design. First, the design of using a square pigtail and a square cylindrical lens effectively improves the space utilization and installation stability of the components. Second, by using a wavelength division multiplexer in conjunction with multiple one-to-one corresponding filter and adjustment plate components, efficient separation and precise adjustment of multi-channel optical signals are achieved, significantly improving signal quality and successfully overcoming the limitations of traditional arrayed waveguide gratings, such as high loss, poor channel quality, and fixed wavelength channels.

The steering prism achieves angular rotation of the signal light, and a limiting lens is used for convergent coupling of the optical signal. This not only optimizes the optical path layout but also improves photoelectric conversion efficiency. The ingenious combination of the array lens and prism further enhances the efficiency of coupling to the photodetector. This design allows the photodetector to be mounted on the side of the substrate, effectively improving space utilization efficiency.

[0025] Furthermore, this invention effectively suppresses echo reflection and achieves precise adjustment of the optical signal angle. By integrating the optical components of the high-speed optical module into a single component, the assembly steps of the optical module are significantly reduced, improving module assembly efficiency. The introduced limiting block design makes the coupling patch of the optical component simpler and more precise. This optical path design not only reduces channel loss but also improves the overall transmission performance of the system, meeting the requirements for flexible wavelength allocation and dynamic routing in optical communication networks, while increasing the transmission rate of the optical module and supporting complex modulation formats.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] Example 1:

[0042] As shown in Figures 1-4, the present invention provides a prism + wavelength division multiplexer assembly (which couples the light to the photodetector) that can better meet the development needs of future optical communication systems, can meet higher transmission rates and more complex modulation formats, while having very low loss and good channel quality.

[0043] The present invention provides an optical component for an optical module, comprising an optical connector assembly 1, an optical fiber 2, a collimating and focusing lens 5, a wavelength division multiplexing (WDM) component 6, a second optical component, and a photodetector 8. The photodetector 8 serves as a receiver. The second optical component consists of a steering prism 9 and a lens 10, and the WDM component 6 is a wavelength division multiplexer. These components, through a specific spatial layout and optical path design, achieve efficient optical signal transmission and processing.

[0044] In terms of optical path layout, the optical connector assembly 1, optical fiber 2, and collimating focusing lens 5 are arranged coaxially in sequence according to the direction of optical signal transmission. The end of optical fiber 2 is provided with a pigtail 3, which has a square design and is located between the collimating focusing lens 5 and the optical connector assembly 1. The collimating focusing lens 5 adopts a square cylindrical lens design, which helps to improve installation stability and space utilization.

[0045] Downstream of the collimating focusing lens 5, a wavelength division multiplexing component 6, a steering prism 9, and a photodetector 8 are arranged in sequence. The wavelength division multiplexing component 6 is equipped with a first filter 6-1, a second filter 6-2, a third filter 6-3, and a fourth filter 6-4. These filters are arranged one-to-one with the optical calibration plate assembly 7 to achieve precise wavelength division of the optical signal.

[0046] The steering prism 9 and lens 10 are an innovative design feature of this invention. The prism comprises two functional components: a steering prism 9 for rotating the signal light angle and a lens 10 connected thereto. The steering prism 9 has an inclined plane at a 135° angle to the light path; this specific angle design allows for precise steering of the light signal. The lens 10 is responsible for converging and coupling the redirected light signal and is arranged in a one-to-one correspondence with the photodetector 8, ensuring efficient transmission of the light signal to the detector. The light signal enters the steering prism 9, is redirected by the steering prism 9, then converged by the lens 10, and finally transmitted to the photodetector 8 for detection and processing; alternatively, the light signal can first pass through the lens 10 and then through the steering prism 9 to the receiving end.

[0047] Furthermore, the entire optical assembly of this invention uses substrate 4 as a carrier platform, and all optical elements are fixed on this substrate. Specifically, the pigtail 3, collimating focusing lens 5, wavelength division multiplexing component 6, and steering prism 9 are all fixed to the upper surface of substrate 4 by adhesive bonding, while the photodetector 8 is adhesively bonded to the side surface of substrate 4. This layout design not only optimizes space utilization but also facilitates device installation and maintenance. The photodetector 8 can also be placed on other devices without being connected to substrate 4.

[0048] In actual operation, after the optical receiver RX port receives the signal source, the optical signal is first transmitted sequentially through the optical connector assembly 1 and optical fiber 2 to the pigtail 3. The light emitted from the pigtail 3 is focused and collimated by the collimating lens 5 before being transmitted to the wavelength division multiplexing (WDM) component 6. Within the WDM component 6, the optical signal is split into signals of different wavelengths by the filtering effects of the first filter 6-1, the second filter 6-2, the third filter 6-3, and the fourth filter 6-4. The optical signal then enters the steering prism 9, which redirects the optical signal, and then it is converged by the lens 10 before finally being transmitted to the photodetector 8 for detection and processing.

[0049] The prism + wavelength division multiplexer assembly design disclosed in this invention significantly reduces optical signal transmission loss and improves channel quality, better adapting to the requirements of future optical communication systems for high-speed transmission and complex modulation formats. All components are fixed to the substrate 4 using a precise adhesive bonding process, ensuring the stability and reliability of the entire optical system.

[0050] Furthermore, the present invention can add a light-adjusting plate assembly 7 between the wavelength division multiplexing component 6 and the steering prism 9. Each light-adjusting plate assembly 7 includes two key parts: a light-adjusting plate base 7-2 and a light-adjusting plate 7-1 mounted thereon, the latter being used for precise fine-tuning of the angle of the signal light. After adding the light-adjusting plate assembly 7, the optical signal in the wavelength division multiplexing component 6 is split into signals of different wavelengths by the filtering effect of the first filter 6-1, the second filter 6-2, the third filter 6-3, and the fourth filter 6-4. These wavelength-splitting signals are transmitted to the corresponding light-adjusting plate assembly 7. After the angle is finely adjusted by the light-adjusting plate 7-1, the optical signal enters the steering prism 9, where the steering prism 9 redirects the optical signal, which is then converged by the lens 10 and finally transmitted to the photodetector 8 for detection and processing.

[0051] Example 2:

[0052] As shown in Figures 5-6, this invention provides another optical component design scheme. This scheme optimizes the optical path structure, reduces the number of optical signal couplings, and further improves the system's transmission efficiency. The specific implementation of this embodiment is described below:

[0053] The optical components provided in this embodiment can be applied to the following optical module, which adopts a two-layer layout design. The upper layer includes an optical connector assembly 1, an optical fiber 2, and a wavelength division multiplexing component 6, while the lower layer is equipped with a photodetector 8. A pigtail 3 is provided at the end of the optical fiber 2, located between the pigtail 3 and the optical connector assembly 1, for achieving stable transmission of optical signals.

[0054] A key innovation of this embodiment lies in the placement of a first optical component between the wavelength division multiplexing (WDM) component 6 and the WDM component 6. This first optical component is a collimating and focusing lens 5, which can be an angled prism lens. Its main function is to focus the output beam and accurately input it to the input of the WDM component 6. By directly bonding the angled prism lens to the WDM component 6, the coupling loss of the optical signal is significantly reduced.

[0055] Between the wavelength division multiplexing component 6 and the photodetector 8, this embodiment incorporates a second optical component for beam redirection and transmission. This component comprises two key parts: a lens 10 and a redirecting prism 9. The lens 10 first converges and couples the beam, and then the redirecting prism 9 redirects the converged beam to the photodetector 8. This "focus first, then redirect" design sequence is another innovation of this embodiment.

[0056] To achieve precise adjustment of the optical signal, a calibration plate assembly 7 is placed between the wavelength division multiplexing component 6 and the second optical component. Each calibration plate assembly 7 consists of two parts: a calibration plate base 7-2 and a calibration plate 7-1 mounted on it. These calibration plate assemblies are arranged one-to-one with the filters on the wavelength division multiplexing component 6, and the angle of the signal light can be precisely fine-tuned through the calibration plate 7-1.

[0057] In actual operation, after the optical receiver's RX port receives the signal light, the optical signal is first transmitted sequentially through the optical connector assembly 1 and optical fiber 2 to the pigtail 3. The light emitted from the pigtail 3 is focused and collimated by an angled prism lens and then transmitted to the wavelength division multiplexing (WDM) component 6. After wavelength division multiplexing by the WDM component 6, the optical signal is transmitted to the corresponding optical adjustment plate assembly 7 for angle fine-tuning. Subsequently, the lens 10 adjusts the focus of the signal light, and finally, the optical signal is transmitted to the photodetector 8 for detection and processing via the steering prism 9. All components are reliably bonded to the substrate 4, ensuring the stability of the system.

[0058] Compared to Embodiment 1, this embodiment has the following two main technical innovations: First, the collimating lens is replaced with an angled prism lens that matches the angle of the wavelength division multiplexing component 6, and it is directly bonded to the wavelength division multiplexing component 6, effectively reducing one optical signal coupling process; Second, in terms of the optical signal processing sequence, a design scheme of focusing first and then steering is adopted, further optimizing the optical transmission efficiency. These innovative designs enable this embodiment to maintain high channel quality while further reducing the system's transmission loss.

[0059] Example 3:

[0060] As shown in Figures 7-8, this invention provides another optical component design scheme. This scheme optimizes the optical path structure, reduces the number of optical signal couplings, and further improves the system's transmission efficiency. The specific implementation of this embodiment is described below:

[0061] The optical components provided in this embodiment can be applied to the following optical module, which adopts a two-layer layout design. The upper layer includes an optical connector assembly 1, an optical fiber 2, and a wavelength division multiplexing component 6, while the lower layer is equipped with a photodetector 8. A pigtail 3 is provided at the end of the optical fiber 2 to achieve stable transmission of optical signals.

[0062] The optical component consists of an angled prism lens directly connected to the wavelength division multiplexing (WDM) component 6. Its main function is to focus the output beam and accurately input it to the input end of the WDM component 6. By directly bonding the angled prism lens to the WDM component 6, the coupling loss of the optical signal is significantly reduced.

[0063] Between the wavelength division multiplexing component 6 and the photodetector 8, this embodiment incorporates a second optical component for beam redirection and transmission. This component comprises two key parts: an integrated lens 10 and a redirecting prism 9. The lens 10 first converges and couples the beam, and then the redirecting prism 9 redirects the converged beam to the photodetector 8. This "focus first, then redirect" design sequence is another innovation of this embodiment.

[0064] Furthermore, the steering prism 9 is composed of four identical prisms. The number of prisms corresponds to the number of beams output by the wavelength division multiplexing component 6. The four identical prisms respectively turn the optical path of the four signal beams, collimate and converge them, and improve the coupling efficiency.

[0065] To achieve precise adjustment of the optical signal, a calibration plate assembly 7 is placed between the wavelength division multiplexing component 6 and the second optical component. Each calibration plate assembly 7 consists of two parts: a calibration plate base 7-2 and a calibration plate 7-1 mounted on it. These calibration plate assemblies are arranged one-to-one with the filters on the wavelength division multiplexing component 6, and the angle of the signal light can be precisely fine-tuned through the calibration plate 7-1.

[0066] In actual operation, after the optical receiver's RX port receives the signal light, the optical signal is first transmitted sequentially through the optical connector assembly 1 and optical fiber 2 to the pigtail 3. The light emitted from the pigtail 3 is focused and collimated by an angled prism lens and transmitted to the wavelength division multiplexing (WDM) component 6. After wavelength division multiplexing by the WDM component 6, the optical signal is transmitted to the corresponding optical adjustment plate assembly 7 for angle fine-tuning. Subsequently, the lens 10 adjusts the focus of the signal light, and finally, the optical signal is transmitted to the photodetector 8 for detection and processing via the steering prism 9. All components are reliably bonded to the substrate 4, ensuring the stability of the system.

[0067] This embodiment has the following two main technical innovations: Compared with the long, integral prism structure used in embodiments 1 and 2, this invention adopts a split structure, in which each channel is separate and independent. These innovative designs enable this embodiment to further reduce the transmission loss of the system while maintaining high channel quality.

[0068] Example 4:

[0069] As shown in Figures 9-10, this invention provides a third optical component design scheme. This scheme innovatively employs a steering collimating lens design, achieving the integration of optical signal collimation and steering functions. The specific implementation of this embodiment is described below:

[0070] The optical components provided in this embodiment can be applied to the following optical module, which also adopts a two-layer layout structure. The upper layer contains an optical connector assembly 1, an optical fiber 2, and a wavelength division multiplexing component 6, while the lower layer contains a photodetector 8. The end of the optical fiber 2 is provided with a pigtail 3 to ensure stable transmission of optical signals.

[0071] This embodiment includes a first optical component, comprising an angled prism lens directly connected to the wavelength division multiplexing (WDM) component 6. The main function of this angled prism lens is to focus the light beam and accurately input it to the input terminal of the WDM component 6. The direct connection between the angled prism lens and the WDM component 6 effectively reduces optical signal coupling loss.

[0072] The core innovation of this embodiment lies in the design of the second optical component. This component employs four steering prisms 9, each possessing the dual functions of beam collimation and focusing, and optical path steering. This innovative design integrates the collimation and focusing functions, which previously required separate operations, into a single device, significantly simplifying the optical path structure. The cross-section of the steering prism 9 can be selected in different shapes according to specific application requirements, including circular, semi-circular, fan-shaped, or polygonal shapes. This flexible design provides more options for different application scenarios.

[0073] In actual operation, after the optical receiver RX port receives the signal light, the optical signal is first transmitted sequentially through the optical connector assembly 1 and optical fiber 2 to the pigtail 3. The light emitted from the pigtail 3 is focused and collimated by the angled prism lens and transmitted to the wavelength division multiplexing (WDM) component 6. After wavelength division processing in the WDM component 6, optical signals of different wavelengths are transmitted to the corresponding steering prisms 9. Each steering prism 9, upon receiving the optical signal, simultaneously performs collimation and focusing as well as optical path steering, directly transmitting the processed optical signal to the photodetector 8 for detection and processing.

[0074] Compared to the previous two embodiments, the main technical innovation of this embodiment lies in the adoption of a more functionally integrated steering prism 9 design. This design not only simplifies the optical path structure and reduces the number of components, but also improves the system's integration and reliability. By integrating collimation, focusing, and optical path steering functions into a single device, the transmission efficiency of the optical signal is further optimized, while also improving the system's space utilization. This innovative design enables this embodiment to achieve a more compact and efficient system structure while maintaining excellent optical performance.

[0075] Example 5:

[0076] As shown in Figures 11-13, this invention provides an optical component design scheme that achieves miniaturization and simplification of assembly process through integrated wavelength division multiplexing (WDM) component design and innovative optical path layout. The optical component provided in this embodiment can be applied to the following optical module, which adopts a two-layer layout structure. The upper layer contains an optical connector assembly 1, an optical fiber 2, and a WDM component 6, while the lower layer contains a photodetector 8. The end of the optical fiber 2 is provided with a pigtail 3, which is located between the WDM component 6 and the optical connector assembly 1.

[0077] The core innovation of this embodiment lies in the integrated design of the wavelength division multiplexing (WDM) component 6. This WDM component 6 is composed of three tightly integrated functional modules: an incident collimating lens 11-1, a WDM multiplexer 11-2, and an exit lens 11-3. The incident collimating lens 11-1 is used for beam collimation and focusing; the WDM multiplexer 11-2 employs a dichroic mirror design to achieve the multiplexing and splitting of optical signals; and the exit lens 11-3 is responsible for collimating and focusing the four signal beams after wavelength division.

[0078] In this embodiment, a prism is used as a second optical component between the wavelength division multiplexing unit 6 and the photodetector 8 to redirect the beam output from the wavelength division multiplexer to the photodetector 8. This design simplifies the optical path structure while ensuring good optical signal transmission performance.

[0079] In actual operation, after the optical receiver's RX port receives the signal light, the optical signal is first transmitted sequentially through the optical connector assembly 1 and optical fiber 2 to the pigtail 3. Subsequently, the optical signal enters the wavelength division multiplexing (WDM) component 6, is focused by the incident collimating lens 11-1, and undergoes wavelength division multiplexing (WDM) processing in the WDM 11-2. The WDM-divided optical signal is then collimated and focused by the exit lens 11-3, and finally, the prism 15 redirects the optical signal to the photodetector 8 for detection and processing. All components are reliably bonded to the substrate 10, ensuring system stability.

[0080] Compared to embodiments 1-4, the main technical innovation of this embodiment lies in replacing the wavelength division multiplexer structure with a dichroic mirror multiplexer, and tightly integrating the incident collimating lens and the output lens array. This design significantly reduces the manufacturing difficulty of component coupling patches, greatly reduces the overall component size, achieves a higher degree of miniaturization, while improving system integration and reliability, simplifying the assembly process, and increasing production efficiency. This highly integrated design not only maintains excellent optical performance but also provides an effective solution for the miniaturization and mass production of optical modules.
