[0025] The following discussion provides various examples of integrated shortwave optical modules and methods of manufacturing thereof. These examples are non-limiting, and the scope of the appended claims should not be limited to the specific examples disclosed. In the following discussion, the terms "example" and "for example" are non-limiting.

[0026] The accompanying drawings illustrate general construction methods, and descriptions and details of well-known features and techniques may be omitted to avoid unnecessarily obscuring this disclosure. Furthermore, elements in the drawings are not necessarily drawn to scale. For example, the dimensions of some elements in the figures may be enlarged relative to other elements to aid in understanding the examples discussed in this disclosure. The same reference numerals denote the same elements in different drawings.

[0027] The term "and / or" refers to any one or more items in a list connected by "and / or". For example, "x and / or y" represents any element in the three-element set {(x), (y), (x, y)}. As another example, "x, y and / or z" represents any element in the seven-element set {(x), (y), (z), (x, y), (x, z), (y, z), (x, y, z)}.

[0028] The terms “comprises”, “comprising”, “including” and / or “containing” are “open-ended” terms and specify the presence of the stated feature, but do not exclude the presence or addition of one or more other features.

[0029] The terms “first,” “second,” etc., may be used herein to describe various elements, and these elements should not be limited by these terms. These terms are used only to distinguish one element from another. Thus, for example, a first element discussed in this disclosure may be referred to as a second element without departing from the teachings of this disclosure.

[0030] Unless otherwise specified, the term "coupled" may be used to describe two elements that are in direct contact with each other or to describe two elements that are indirectly connected by one or more other elements. For example, if element A is coupled to element B, then element A may be in direct contact with element B or indirectly connected to element B through an intermediate element C. Similarly, the terms "above" or "over" may be used to describe two elements that are in direct contact with each other or to describe two elements that are indirectly connected by one or more other elements.

[0031] In recent years, with the rapid development and popularization of technologies such as 5G communication, IoT, cloud computing, big data, and next-generation AI, the demand for network capacity has grown exponentially.

[0046] Now for reference Figure 1A , Figure 1A It is an exemplary shortwave module 1 according to this disclosure. Figure 1A The system may include a platform 10, a glass spacer 20, an optical collimation module 30, an optical reflection module 40, and a lens array 50. The optical collimation module 30 may include an optical fiber array 31, a lens array 32, a spacer 33, and an air gap 34. The lens array 50 may include a transmitting lens 51 and a receiving lens 52. The optical fiber array 31 is operable to receive one or more optical fibers / fiber cores 5.

[0047] The optical collimation module 30 and the optical reflection module 40 can be fixed to the upper side of the platform 10, for example, with optical adhesive. The spacer 20 and the lens array 50 can be fixed to the lower side of the platform 10. For example, the spacer 20 can be bonded to the platform 10 with adhesive. The emitting lens 51 and the receiving lens 52 can be directly molded onto the platform 10 using a polymer on glass (POG) process or a nanoimprinting process. The lens array 50 can also be produced by molding, embossing, or etching.

[0048] For example, platform 10 may include fused silica. Optical collimation module 30 may include, for example, multiple optical fiber cores received by optical fiber array 31. For example, an MT connector may be used to attach optical fiber core 5 to optical fiber array 31. Lens array 50 and spacer 20 may be formed of monocrystalline silicon. Depending on the requirements of the application, i.e., the number of channels / fibers, lens array 50 may be one-dimensional or two-dimensional. Lens array 50 may be made of polymer. For example, optical reflection module 40 may include 45 o A rhomboid prism. The light reflecting module 40 may include an anti-reflective film coated on the outer surface of the rhomboid prism (away from the light collimating module 30). The platform 10 may typically be rectangular. The platform 10 may be trapezoidal or circular. The platform 10 may be made of a glass substrate, and the lens array 50 may be bonded to or imprinted onto it.

[0049] like Figure 1A As shown, the spacer 20 can be fixed to the underside of the platform 10. The dimensions of the spacer 20 can be based on the focal length of the lens array 50 and the position of the signal receiver (not shown) below the platform 10. The spacer 20 can be made of glass, silicon, or ceramic.

[0050] Fiber optic array 31 is operable to receive one or more optical fibers 5. The optical fibers 5 may have a specific pitch. Typically, the number of optical fibers is greater than two. Fiber optic array 31 is operable to couple optical signals to shortwave module 1. Fiber optic array 31 may be one-dimensional or two-dimensional. Air gap 34 may be air, or may include a combination of air and optical materials. Lens array 32 may include one or more lenses, typically made of polymer. Lens array 32 may be formed using a POG process, which may eliminate the need for adhesives.

[0051] The light reflection module 40 may include a reflecting prism (e.g., a rhomboid prism, such as...). Figure 1A As shown), right-angle prism (such as...) Figure 1E (As shown), a diamond prism or other suitable prism shape. The reflecting prism can be made of glass or other transparent optical materials. The light reflecting module 40 is operable to reflect horizontally incident light signals from the light collimating module 30 to the lens array 50 (and vice versa). In some cases, the light reflecting module 40 may include multiple reflecting prisms (such as...). Figure 1F (As shown). In this case, the reflecting prisms can be glued together, for example.

[0052] Optionally, a beam splitter module may be located between the optical collimation module 30 and the optical reflection module 40 (not shown). The beam splitter module may include, for example, a Z-shaped block and may be made of glass, silicon, or other transparent optical materials.

Also optionally, an optical shrinking module may be located between the optical collimation module 30 and the optical reflection module 40. The optical shrinking module may include multiple wedge prisms and / or curved lenses. The optical shrinking module may be made of glass, silicon, or other transparent optical materials. The optical shrinking module is operable to change the diameter of the signal beam spot. This may be advantageous for signal channel spacing.

The optical deflection module may include tilted parallelogram prisms and may be made of glass, silicon, or other transparent optical materials. The optical deflection module can be used to create a fixed-size spacing in the radial direction by reflecting signal light of different wavelengths.

[0053] Using the POG process on shortwave module 1 can reduce product installation time, improve integration and miniaturization, and lower product costs. The advantages of glass components include high transmittance and low insertion loss, high thermal stability, low coefficient of thermal expansion (e.g., compared to plastic polymers used in injection molding), strong scalability, and applicability to molding, edging, embossing, and coating processes. For example, this approach may be suitable for low-cost, high-volume production by employing high-precision automated assembly.

[0054] Figure 1B Various embodiments according to this disclosure are shown. Figure 1A The illustrated structure demonstrates the exemplary function of the emitted optical path. An emitted optical path for a wavelength λ1 is also shown, as indicated by the dashed arrow.

[0055] The transmitted optical signal can travel from optical fiber 5 through optical fiber array 31, air gap 34, lens array 32, and spacer 33 to reach optical reflection module 40. Lens array 32 can collimate the transmitted optical signal passing through it. The transmitted optical signal can enter optical reflection module 40 perpendicularly and be redirected to transmitting lens 51. According to various embodiments of this disclosure, one or more transmitting optical paths can correspond to one or more transmitted optical signals.

[0056] Figure 1C Various embodiments according to this disclosure are shown. Figure 1A The illustrated structure demonstrates the exemplary function of the receiving optical path. A receiving optical path for an optical signal with wavelength λ1 is also shown, as indicated by the dashed arrow.

[0057] The received optical signal can be received, for example, from a laser at the receiving lens 52. The wavelength of the received optical signal can be λ2. The received optical signal can be collimated by the receiving lens 52 and reflected towards the spacer 33 at the surface 402 of the light reflecting module 40. The received optical signal can be refracted at the surface 401. Then, the received optical signal can pass through the spacer 33, the lens array 32, the air gap 34, and be coupled to the optical fiber 5 in the optical fiber array 31. According to various embodiments of the present disclosure, the spacer 33 and the air gap 34 may not exist in the receiving optical path. According to various embodiments of the present disclosure, one or more receiving optical paths may correspond to one or more received optical signals.

[0058] Figure 1D Exemplary functionality of multiple transmission paths according to various embodiments of this disclosure is illustrated. Two transmission optical paths are also shown, as indicated by dashed arrows.

[0059] exist Figure 1D The diagram shows a cross-section of an embodiment of the present disclosure including a two-dimensional fiber array 31. For example, the fiber array 31 may be operable to receive 24 fibers arranged in a 12-row by 2-column configuration. Correspondingly, the lens array 32 may also include an equal number of lenses, i.e., 24 in this example. For example, the lens array 32 and the spacer 33 may be made of monocrystalline silicon. Multiple emitted light paths / signals may be reflected and redirected to the lens array 50 at a surface 401 of the light reflection module 40. A reflective coating may be present on surface 401.

[0060] Figure 1E Exemplary embodiments of shortwave modules according to various embodiments of this disclosure are shown. A module including 45... oA right-angle prism light-reflecting module 40. The emitted light signal is shown as indicated by the dashed arrow. According to various embodiments of the invention, the emitted light signal is reflected and redirected to a lens 50 on the surface 401 of the light-reflecting module 40. According to various embodiments of this disclosure, one or more emitted light paths may correspond to one or more emitted light signals, which can be redirected to the lens array 50.

[0061] Figure 1F Exemplary embodiments of a shortwave module according to various embodiments of the present disclosure are shown. A light-reflecting module 40 including multiple rhombic prisms 41, 42, and 43 is shown. According to various embodiments of the present disclosure, surfaces 401, 402, 403, and 404 may be coated with films that reflect different wavelengths. In this figure, dashed arrows may represent mixed wavelength signals. Depending on the wavelength of the reflecting surface, the mixed wavelength signal can be reflected and redirected on one of the surfaces 401, 402, 403, and 404. In this way, each reflecting surface can reflect and redirect only a specific range of wavelengths to one or more lenses of the lens array 50. Therefore, this arrangement is advantageous for separating signals of different light wavelengths into separate channels.

[0062] Figure 2A Exemplary embodiments of a shortwave module according to various embodiments of the present disclosure, including a beam splitter prism, are shown. A beam splitter prism 60 is also shown. The beam splitter prism 60 may be made of optical glass.

[0063] Figure 2B It shows Figure 2A The illustrated embodiment demonstrates the function of a transmitted optical signal comprising multiple wavelengths, as indicated by the dashed arrows. The optical signal can be transmitted from the fiber array 31 through an air gap 34, a lens 32, and a spacer 33 to a beam splitter 60. In the beam splitter 60, the optical signal can be reflected twice and split into a first signal portion corresponding to a first wavelength and a second signal portion corresponding to a second wavelength. As shown, the first and second signal portions can exit from the beam splitter 60 at different physical locations. Due to these different physical exit locations of the beam splitter 60, the first and second signal portions also reflect light in the light reflection module 40 (exemplary 45 is shown). o The light reflects off at different physical locations within the right-angle prism and can therefore be guided to different lenses 51, 52 of the lens array 50. Similar to... Figure 1F The implementation shown has the advantage of separating signals of different wavelengths into different channels.

[0064] Figure 3A An exemplary embodiment according to this disclosure is shown, which also includes a light contraction module 70. The light contraction module 70 can be configured to reduce the diameter of the incident beam at its output end.

[0065] Figure 3B It shows that according to Figure 3A The implementation describes the function of the shortwave module. In the beam splitter 60, multi-wavelength incident light signals can be separated into multiple beams according to wavelength. An exemplary beam splitter 60 displaying two outgoing beams of different wavelengths is shown. The beam diameters of the two beams incident on the light contraction module 70 can be reduced in the light contraction module 70, so that the beam exiting the light contraction module 70 shown can have a smaller beam diameter. For example, the light contraction module 70 can be used to improve the physical separation between the beams.

[0066] Figure 4A An exemplary embodiment according to this disclosure is shown, which also includes an optical deflection prism 80.

[0067] Figure 4B It shows Figure 4A A partial top view of the illustrated embodiment. A lens array 50 is shown, comprising multiple sets of interleaved lens arrays 51 and 52. A fixed pitch may exist between lens arrays 51 and 52. For example, the fixed pitch may be 250 μm. Lens arrays 51 and 52 can be used, for example, to receive optical signals of different wavelengths. Optical signals of different wavelengths can be optically coupled from a beam splitter 60 to lens arrays 52 and 51. For example, lens arrays 51 and 52 can be made of organic polymers and / or can be mass-molded on platform 10 using a POG process.

[0068] Figure 4C It shows Figure 4A The exemplary embodiment shown demonstrates functionality. For example, at least two beams of different wavelengths can exit from the beam splitter 60. These at least two beams can be incident on the optical deflector 80. The optical deflector 80 is operable to align the two beams at its output in the vertical dimension, as shown, with the two beams exiting from the optical deflector 80 at the same vertical level. However, the two beams can be separated in the horizontal dimension. For example, one of the two beams can be incident on lens array 52, while the other beam can be incident on lens array 51, as... Figure 4B The interlaced lens arrays 51 and 52 are shown in the middle.

[0069] Figure 4D This demonstrates the lateral deflection effect of the deflecting prism 80 on light. Figure 4A A partial top view.

[0070] Figure 5A Exemplary shortwave optical modules according to various embodiments of the present disclosure are shown. Figure 5B It shows Figure 5A The functionality of the exemplary implementation. Figure 5A and Figure 5B They can be similar to each other. Figure 2A and Figure 2B The difference is that, Figure 5A and Figure 5B A beam splitter 60 is shown, which is operable to split incident light into three different output beams according to three different wavelengths. Figure 2A and Figure 2B Two wavelengths are shown. Accordingly, lens array 50 may include at least three lenses / lens arrays 51, 52, and 53.

[0071] Figure 6A The illustration shows a shortwave optical module according to various embodiments of the present disclosure, which also includes a trapezoidal light reflection module 40. Figure 6B It shows that according to Figure 6A The operation of the disclosed implementation is shown. Dashed arrows are shown to indicate the emitted light path and signal. The light reflecting module is configured to include (partially) reflective surfaces 401 and 402. A first portion of the light incident on the light reflecting module 40 can be reflected and redirected toward the lens 51 at surface 401. A second portion of the light incident on the light reflecting module 40 can be reflected and redirected toward the lens 52 at surface 402. This configuration is advantageous for splitting the light beam incident on the light reflecting module 40 into two channels. For example, the light reflecting module 40 can act as a beam splitter that can split the light beam into two channels, each channel including an incident light signal of a certain power.

[0072] This disclosure includes references to certain examples; however, those skilled in the art will understand that various changes can be made and equivalents can be substituted without departing from the scope of this disclosure. Furthermore, modifications can be made to the disclosed examples without departing from the scope of this disclosure.
