Abstract
Description
Technical Field
[0001] This application relates to the field of optical connector technology, and particularly to an optical connector assembly applicable to optoelectronic integrated circuits.
Background Art
[0002] Optoelectronic integrated circuits (OEICs) utilize photons instead of electrons for computing and data transmission within integrated circuits, bringing great benefits to the development of industries requiring high-performance data exchange, long-distance interconnections, 5G facilities, and computing devices. An OEIC is composed of a photonic integrated circuit (PIC) and an electronic integrated circuit (EIC), and can be co-packaged as co-packaged optics (CPO).
[0003] Conventional co-packaged optics are usually connected to optical fibers for optical transmission. The optical fibers are directly connected to the optoelectronic integrated circuit of the co-packaged optics. However, direct optical coupling between the optical fiber and the optoelectronic integrated circuit is likely to cause damage to the surface of the optoelectronic integrated circuit due to contact with the optical fiber. That is, the optical fibers connected to conventional co-packaged optics are not actually suitable for frequent insertion and extraction into the co-packaged optics. Furthermore, direct optical coupling between the optical fiber and the optoelectronic integrated circuit is disadvantageous for adjusting the numerical aperture of the optical path between the optical fiber and the optoelectronic integrated circuit, and thus the optical coupling efficiency cannot be improved.

Unless otherwise specified, these terms are only used to distinguish one element from another. Therefore, for example, the first element, the first component, or the first part discussed below may be referred to as the second element, the second component, or the second part without departing from the teachings of the present application. Furthermore, the present application may refer to reference numbers and / or letters repeatedly in various examples. Such repetition is for the purpose of simplicity and clarity and does not itself determine the relationship between the various embodiments and / or configurations discussed.
[0024] The present invention provides an optical connector assembly applicable to connection to a data processing device or data sharing device, such as a switch or server, where one of the data processing device or data sharing device comprises an optoelectronic integrated circuit. Referring to Figure 1, Figure 1 is an exploded perspective view of an optical connector assembly 100 applicable to an optoelectronic integrated circuit according to an embodiment of the present invention, the optical connector assembly 100 includes a first connector 1 and an optical transmission device 3. The first connector 1 is optically mounted on one side of the optoelectronic integrated circuit 51, and the optical transmission device 3 is detachably and optically connected to the first connector 1 and is used for optical communication between the optoelectronic integrated circuit 51 and the application product to which the optical transmission device 3 is connected. In some embodiments, the optoelectronic integrated circuit 51 may be, but is not limited to, a silicon photonic optoelectronic integrated circuit.
[0025] Referring to Figures 2 and 3, and in combination with Figure 1, the first connector 1 includes a base 11 and a waveguide device 20. The base 11 is mounted on one side of the optoelectronic integrated circuit 51, and the waveguide device 20 is mounted on the base 11 and optically coupled to the optoelectronic integrated circuit 51. The base 11 is rectangular and includes a front end 111, a rear end 112, and a bottom plate 113, which are mounted relative to each other. The front end 111 is the surface of the base 11 for bonding to the optoelectronic integrated circuit 51. In some embodiments, the base 11 is made from a material with high temperature resistance, such as ceramics or a metal, such as zirconium dioxide (ZrO2). Alternatively, the base 11 may be made from a non-metallic material, such as an organic adhesive (e.g., resin), polymer, or plastic.
[0026] As shown in Figure 2, the first connector 1 further includes an engaging member 15, which is mounted on the rear end 112 of the base 11, away from the optoelectronic integrated circuit 51. Specifically, the engaging member 15 extends integrally from the rear end 112 away from the front end 111 and is mounted perpendicular to the rear end 112. The engaging member 15 includes an engaging projection 151. In some embodiments, the engaging projection 151 is located on the upper surface of the engaging member 15, protrudes upward from the upper surface of the engaging member 15, and has a block-like shape. The engaging projection 151 is spaced away from the rear end 112, and a retaining space 150 is formed between the engaging projection 151 and the rear end 112. Preferably, the engaging projection 151 has a rear surface, which is bent or inclined with respect to the upper surface of the engaging member 15 to facilitate assembly with the optical transmission device 3. In this embodiment, the projection of the engaging projection 151 onto one plane falls entirely within the vertical projection of the engaging member 15, resulting in a smaller dimension and the formation of an approximately U-shaped region around the engaging projection 151, thereby improving the assembly strength with the optical transmission device 3.
[0027] Continuing to refer to Figure 2, the base 11 includes a pair of spaced-apart positioning walls 14 that extend integrally downward from the base 11, and the bottom plate 113 is connected between the positioning walls 14. A rectangular groove 115 is provided at the rear end 112 of the base 11, away from the optoelectronic integrated circuit 51, and the rectangular groove 115 is adjacent to the positioning wall 14. The rectangular groove 115 is located below the engaging member 15 and is used to prevent the optical transmission device 3 from being displaced vertically (shown in Figure 5, which will be described in detail later). As shown in Figure 2, the first connector 1 further includes two positioning sections 13, which are mounted on the positioning wall 14 and spaced apart from each other. Each positioning section 13 extends through the rear end 112 of the base 11 and is exposed in the rectangular groove 115. In some embodiments, the positioning sections 13 are groove-shaped.
[0028] As shown in Figures 1 to 3, the base 11 has a recess 12 that is recessed from its front end 111 and adjacent to the optoelectronic integrated circuit 51. In this embodiment, as shown in Figure 3, the waveguide device 20 is mounted in the recess 12. Specifically, the positioning wall 14, the bottom plate 113, and the rear end 112 of the base 11 surround the recess 12, the recess 12 penetrates the rear end 112, and is exposed at the front end 111, top, and rear end 112 of the base 11. The waveguide device 20 is installed in the recess 12, and a part of the waveguide device 20 extends from the bottom plate 113 and is exposed at the rear end 112. As shown in Figure 2, a plurality of optical waveguides 201 are installed inside the waveguide device 20 and are used for transmitting optical signals. Specifically, an optical coupling surface is defined at the front end of the waveguide device 20, and the optical coupling surface is an inclined surface relative to the optoelectronic integrated circuit 51, preferably inclined at 8 degrees to prevent interference of reflected light during the optical transmission process.
[0029] In some embodiments, the recess 12 can be omitted, meaning the waveguide device 20 can be mounted directly on the upper surface of the base 11. Without the recess 12, the assembly efficiency and strength of the waveguide device 20 on the base 11 are inferior to those with the recess 12 on the base 11.
[0030] The waveguide device 20 is preferably made from a material containing, for example, silicon dioxide. Alternatively, the waveguide device 20 may be made from a material containing SOI (Silicon On Insulator), lithium niobate (LiNbO3), or a polymer. The waveguide device 20 may be formed using materials such as fused silica, quartz, glass, or borosilicate glass. In some embodiments, the waveguide device 20 includes a planar optical wave conduit (PLC). In some embodiments, the planar optical wave conduit can be configured in a variety of ways, including but not limited to linear optical paths, optical splitters, array waveguide diffraction grating wavelength division multiplexers, and cross-connect optical paths. The planar optical wave conduit in embodiments of the present application may employ different types of waveguides or devices.
[0031] Referring to Figure 4, and combining it with Figure 1, Figure 4 is a perspective view of the optical transmission device 3 of the optical connector assembly 100. The optical transmission device 3 includes a plurality of optical fibers 31, a second connector 32, a plurality of positioning members 33, a plurality of limiting members 34, and a movable fastening member 35. Specifically, the second connector 32 is installed at one end of the optical fiber 31 and is used to terminate the optical fiber 31 and to connect it detachably to the first connector 1. In some embodiments, the second connector 32 includes a body 321 and a plurality of support members 323. In detail, the support members 323 extend upward from the upper surface of the body 321. The support members 323 are spaced apart from each other, and each support member 323 includes a first stage 3231 and a second stage 3233. The second stage 3233 is adjacent to the first stage 3231, and the position of the second stage 3233 is higher than that of the first stage 3231. The support member 323 is used to facilitate the assembly of the second connector 32 and the first connector 1, which will be explained further later.
[0032] As shown in Figure 4, the two positioning members 33 are spaced apart and extend forward from the front surface of the main body 321. In this embodiment, the positioning members 33 are pin-shaped, and their shape and dimensions are adapted to fit tightly into and insert into the groove-shaped positioning portion 13 of the base 11. The optical fiber end 310 of the optical fiber 31 is exposed on the front surface of the main body 321 located between the positioning members 33.
[0033] As shown in Figures 1 and 4, in this embodiment, the movable fastening member 35 is movably connected to the main body 321 via a restricting member 34. Specifically, the two restricting members 34 are installed on the rear side of the main body 321 opposite the optical fiber end 310. Specifically, one end of the restricting member 34 is connected to the rear side of the main body 321, and the other end of the restricting member 34 is located away from the rear side of the main body 321. In this embodiment, each restricting member 34 includes a restricting rod 341 and an elastic member 342. One end of the restricting rod 341 is connected to the rear side of the main body 321, and the elastic member 342 is located on the restricting rod 341. Preferably, the elastic member 342 is a compression coil spring, and the restricting rod 341 is inserted into the elastic member 342. The elastic member 342 may deform along the longitudinal direction of the restricting rod 341 due to pressure applied by the movable fastening member 35, or when the pressure applied by the movable fastening member 35 is released.
[0034] Referring again to Figures 1 and 4, the movable fastening member 35 may be made from a material including metal, plastic, or ceramic. Specifically, the movable fastening member 35 includes a cover portion 351 located above the main body 321, a connecting portion 353 movably connected to the main body 321, and a bent portion 352 connected between the cover portion 351 and the connecting portion 353. Preferably, the cover portion 351, the bent portion 352, and the connecting portion 353 are integral elements and together generally form an inverted L-shaped cantilever structure. A fastening groove 350 is formed on the cover portion 351 and penetrates the cover portion 351, and the shape and dimensions of the fastening groove 350 are designed to mate and engage with the engaging projection 151 of the first connector 1. Specifically, the connecting portion 353 is detachably attached to the limiting member 34 and can move from the other end of the limiting member 34 to the rear side of the main body 321.
[0035] Referring to Figure 5, the movable fastening member 35 includes two spaced-apart retaining structures 354, the two retaining structures 354 extending from the bottom of the connecting portion 353. In this embodiment, each retaining structure 354 includes a pair of arm portions 3541, with an engagement groove 3543 provided between the arm portions 3541. The shape and dimensions of the arm portions 3541 and the engagement groove 3543 are designed to fit with the limiting rod 341. One end of the elastic member 342 abuts against the rear side of the main body 321, and the other end of the elastic member 342 abuts against the connecting portion 353. Specifically, the engagement groove 3543 is provided along the lower edge of the retaining structure 354, and the upper width of the engagement groove 3543 is greater than the lower width, positioning the retaining structure 354 vertically on the limiting rod 341. The diameter of the rear end of the limiting rod 341 is greater than the upper width of the engagement groove 3543, positioning the retaining structure 354 laterally between the rear end of the limiting rod 341 and the elastic member 342. In this way, the movable fastening member 35 can move from a position away from the main body 321 to the rear side of the main body 321, or from the rear side of the main body 321 to a position away from the main body 321, that is, the connecting portion 353 is movable within the length range of the limiting rod 341.
[0036] As shown in Figures 4 and 5, the cover portion 351 includes two wing portions 355, which are positioned on two relative sides of the cover portion 351 and bend downward toward the main body 321. When the wing portions 355 are not fastened to the first connector 1, they are each supported on the support members 323. Specifically, the rear ends of the wing portions 355 abut against the second stage portion 3233, tilting the cover portion 351 relative to the main body 321, thereby increasing the space between the cover portion 351 and the main body 321, and facilitating the assembly of the second connector 32 and the first connector 1.
[0037] Referring to Figures 5 and 6, and combining them with Figure 1, Figure 6 is an assembled perspective view of the optical connector assembly 100 of Figure 1 installed on the substrate 50. The optical transmission device 3 is detachably connected to the first connector 1 in a direction perpendicular to the thickness direction T of the waveguide device 20 (see Figure 3). Specifically, the cover portion 351 moves together with the connecting portion 353 and fastens to the engaging member 15, so that the engaging member 15 is positioned between the cover portion 351 and the body 321 of the second connector 32. More specifically, the cover portion 351 is moved forward toward the first connector 1, and the positioning member 33 is tightly inserted into the positioning portion 13. At the same time, the cover portion 351 is guided by the engaging projection 151. As the cover portion 351 is pushed forward until it reaches the retaining space 150, the cover portion 351 is pushed downward, the fastening groove 350 engages with the engaging projection 151, and the front part of the cover portion 351 is positioned within the retaining space 150. Simultaneously, as shown in Figure 6, after the engaging projection 151 and the cover portion 351 engage via the fastening groove 350, the rear end of the wing portion 355 is held on the second connector 32 and positioned in front of the first stage portion 3231, and the elastic member 342 provides thrust to the holding structure 354, appropriately tightening the engagement between the cover portion 351 and the engaging projection 151. In this way, the second connector 32 is easily and securely connected to the first connector 1.
[0038] The assembly of the optical connector assembly 100 and the optoelectronic integrated circuit 51 mounted on the substrate 50 will be described in detail below. First, the first connector 1 connected to the optical transmission device 3 is positioned on the optoelectronic integrated circuit 51, and the first connector 1 is actively aligned with the optical monitoring signal transmission portion (unsigned) of the optoelectronic integrated circuit 51, so that the optical transmission device 3 transmits signals to the optoelectronic integrated circuit 51 via the waveguide device 20. That is, the optical signal is optically coupled to the optoelectronic integrated circuit 51 via the waveguide device 20, and is not transmitted directly to the optoelectronic integrated circuit 51. This improves the change in the numerical aperture of the optical path when the optical signal is transmitted from the optical fiber 31 to the optoelectronic integrated circuit 51, and also prevents the optoelectronic integrated circuit 51 from being damaged by direct contact between the optical fiber 31 and the second connector 32 during the repeated insertion and removal process of the second connector 32.
[0039] Furthermore, when direct optical signal transmission is established between the optical fiber 31 and the optoelectronic integrated circuit 51, the material properties and structure of the optoelectronic integrated circuit 51 significantly hinder the range of change in the numerical aperture of the optical path. However, this is a problem that can be solved by the detachable structure of the base 11 and waveguide device 20 as described above. Moreover, since the base 11 and waveguide device 20 are installed separately from the optoelectronic integrated circuit 51, the manufacturing of the first connector 1 is separated from the optoelectronic integrated circuit, which is advantageous for improving production efficiency and is also advantageous for custom production, compared to cases where an optical path is not directly formed in the optoelectronic integrated circuit and a waveguide device is not placed.
[0040] Referring to Figure 7, and combining it with Figure 1, when the optical transmission device 3 is removed, the fastening groove 350 is moved upward to disengage from the engaging projection 151, and the elastic member 342 automatically pushes the connecting portion 353 away from the second connector 32. After that, the second connector 32 can be removed from the base 11. Specifically, after positioning the first connector 1 on the optoelectronic integrated circuit 51, the optical transmission device 3 is removed from the first connector 1, and at least one reflow soldering process or one back-end process is performed with the first connector 1 and the optoelectronic integrated circuit 51 coupled to the substrate 50. After the optoelectronic integrated circuit 51 with the first connector 1 is co-packaged with the substrate 50, the optical transmission device 3 is reinserted into the first connector 1 to realize optical signal transmission between the optoelectronic integrated circuit 51 and the optical transmission device 3. In this way, the optical transmission device 3 is not damaged by the high temperature during the above process.
[0041] Referring to Figures 8 and 9, Figure 8 is an exploded perspective view of an optical connector assembly 100' installed on a substrate 50 according to an embodiment of the present invention, and Figure 9 is a schematic cross-sectional view showing multiple optical connector assemblies 100' from Figure 8. The main difference between optical connector assembly 100' and optical connector assembly 100 is that the first connector 1' includes a bridge element 16 and multiple base limiting sections 116. Note that other components of optical connector assembly 100' are the same as those of optical connector assembly 100 and will not be described in detail here. In order to clearly show the connection between the base limiting section 116 and the optoelectronic integrated circuit 51, the bridge element 16 is omitted in Figure 9. As shown in Figure 8, the base 11' further includes the bridge element 16 and is used to connect the optoelectronic integrated circuit 51 and the waveguide device 20. Specifically, a portion of the bridge element 16 is installed in the recess 12 and located on the waveguide device 20 covered by the bridge element 16, while another portion of the bridge element 16 extends a certain length onto the optoelectronic integrated circuit 51, so that a portion of the optoelectronic integrated circuit 51 is sandwiched between the bridge element 16 and the substrate 50. In other words, the role of the bridge element 16 is to reinforce the structural strength of the optoelectronic integrated circuit 51 and provide a structural force that connects the optoelectronic integrated circuit 51 and the waveguide device 20 together, ensuring a reliable optical connection between the optoelectronic integrated circuit 51 and the waveguide device 20, especially when the optoelectronic integrated circuit 51 is too thin and could cause warping of the optoelectronic integrated circuit 51.
[0042] In some other embodiments, the optoelectronic integrated circuit 51 has sufficient thickness to withstand warping, and the optical connector assembly 100' does not include the bridge element 16 but includes the base limiter 116.
[0043] As shown in Figures 8 and 9, the base 11 includes a pair of spaced-apart base limiters 116, which protrude from the front end of the base 11. The base limiters 116 are located above the optoelectronic integrated circuit 51, and the bridge element 16 is positioned between the base limiters 116. The base limiters 116 are used to prevent the first connector 1 from being displaced vertically and to ensure that the bridge element 16 is held within the recess 12.
[0044] Referring to Figure 10, which is a schematic diagram of a structure in which multiple optical connector assemblies 100' from Figure 8 are installed on a substrate 50, in other embodiments, four optoelectronic integrated circuits 51 can be installed on each side of the substrate 50, and each optoelectronic integrated circuit 51 is connected to an optical connector assembly 100 / 100' (not shown). The number of optoelectronic integrated circuits 51 may change as needed.
[0045] Therefore, by separately installing the base and the waveguide device, the present invention makes it possible to repeatedly insert and remove the optical transmission device from a first connector mounted on an optoelectronic integrated circuit, without damaging the optoelectronic integrated circuit, and ensuring that the numerical aperture of the optical path formed by the optical fiber, waveguide device and optoelectronic integrated circuit has a much wider adjustment range than that which occurs when the optical fiber and the optoelectronic integrated circuit directly employ optical coupling, thereby improving optical transmission performance.

Therefore, the scope of the Disclosure is not limited to these embodiments. The scope of the Disclosure should be interpreted as being based on the claims, and all technical ideas that are the same as or equivalent to the above-described scope should be interpreted as being included within the scope of the Disclosure.
