Description

Technical Field

[0001] This utility model relates to an optical fiber connector, and more particularly to a co-encapsulated photonic optical fiber connector. Background Technology

[0002] Co-packaged Optics (CPO) is a technology that integrates optical and electronic components onto a single substrate. It aims to improve data transmission efficiency, reduce power consumption and cost, and shrink system size. CPO reduces optical signal loss caused by traditional packaging by more tightly integrating optical components into the electronic chip, while simultaneously increasing signal transmission speed and bandwidth. Furthermore, by shortening the optical signal transmission path, CPO can reduce the energy required for signal transmission, thereby lowering overall power consumption. Utility Model Content

[0003] This invention provides a co-encapsulated photonic fiber optic connector, which allows the fiber optic assembly and photonic integrated circuit to be quickly combined or separated without damaging the fiber optic assembly through the assembly and disassembly of the fixing mechanism.

[0004] This invention relates to a co-packaged photonic fiber optic connector, configured on a photonic integrated circuit (PIC) to receive and optically couple fiber optic assemblies to the PIC. The co-packaged photonic fiber optic connector includes a housing, an intermediary, and a spring. The housing is mounted on the PIC and has a shaft and a slot, the fiber optic assembly being adapted to be inserted into or removed from the slot. The intermediary is inserted into the slot to cover or remove the fiber optic assembly. A portion of the spring is pivotally hooked to the shaft, allowing the spring to pivot relative to the housing along the shaft. In the fixed state, the fiber optic assembly and the intermediary are inserted into the slot, with at least another portion of the spring abutting against the intermediary to secure the fiber optic assembly in the slot via the intermediary.

[0005] Due to the adoption of the above technical solution, this utility model has the following beneficial effects: Based on the above, the co-packaged photonic fiber optic connector utilizes a mechanism where a spring is assembled to the housing and can pivot relative to the housing. After the fiber optic assembly is inserted into the slot, and an intermediary is also inserted into the slot to cover the fiber optic assembly, the spring can be pivoted and secured to at least one of the housing and the intermediary. This allows the spring's elasticity to press against the fiber optic assembly through the intermediary, thus fixing the fiber optic assembly in the slot of the housing. Besides enabling quick assembly and disassembly of the fiber optic assembly and photonic integrated circuit through the cooperation of the spring, housing, and intermediary, the spring pivoted on the housing abuts against the intermediary, effectively protecting the fiber optic assembly with the intermediary. This provides a stable assembly mechanism for the fiber optic assembly and photonic integrated circuit and extends the lifespan of the fiber optic assembly. Attached Figure Description

Detailed Implementation

[0021] Figure 1A This is a schematic diagram of a co-packaged photonic fiber optic connector according to an embodiment of the present invention. Figure 1B Drawing from another perspective Figure 1A Co-packaged photonic fiber optic connectors. Figure 1C Draw Figure 1A Another state of the co-packaged photonic fiber optic connector. Please also refer to... Figures 1A to 1C This embodiment also provides Cartesian coordinates XYZ for ease of component description. A co-packaged photonic fiber optic connector 100 is disposed on the photonic integrated circuit 300 to receive the fiber optic assembly 200 and optically couple the fiber optic assembly 200 to the photonic integrated circuit 300. Here, the photonic integrated circuit 300 (PIC) utilizes semiconductor processes to directly fabricate optical components such as modulators, switches, and beam splitters within an integrated circuit, forming a compact optoelectronic integrated circuit element. Unlike electronic integrated circuits that transmit electrons, integrated optical elements primarily transmit optical signals in the visible or infrared bands, and the connections between components in the circuit are accomplished by optical waveguides. Through these miniaturized and highly stable integrated optical elements, optoelectronic communication systems can play an increasingly important role and function.

[0022] Figure 2A This is an exploded view of a co-packaged photonic fiber optic connector. Please also refer to... Figure 1A , Figure 1C and Figure 2A In this embodiment, the co-encapsulated photonic fiber optic connector 100 includes a housing 110, an intermediary 120, and a spring 130. The housing 110 is mounted on the photonic integrated circuit 300 and has a shaft 111 and a slot 112, through which the fiber optic assembly 200 is adapted to be inserted into or removed from the slot 112. The intermediary 120 is inserted into the slot 112 to cover the fiber optic assembly 200 or to be removed from the slot 112. A portion of the spring 130 is pivotally hooked to the shaft 111, allowing the spring 130 to pivot relative to the housing 110 along the shaft 111. In this embodiment, the housing 110 is situated on the XY plane, while the shaft 111 is parallel to or aligned with the X-axis. In a fixed state (e.g. Figure 1A or Figure 1B As shown), the fiber optic assembly 200 and the intermediary 120 are moved into and inserted into the slot 112 in the negative Y-axis direction. The spring tab 130 pivots relative to the X-axis so that at least another part of it abuts against the intermediary 120, thereby securing the fiber optic assembly 200 in the slot 112 via the intermediary 120. Conversely, when the spring tab 130 pivots relative to the housing 110 and moves away from the intermediary 120, as... Figure 1C As shown, the intermediary 120 and the fiber optic assembly 200 can then be pulled out of the slot 112 in the positive Y-axis direction.

[0023] Furthermore, such as Figure 2A As shown, the outer casing 110 has two side walls 113 forming a slot 112 and an inner stop surface S1, the two side walls 113 facing each other, and the inner stop surface S1 abutting between the two side walls 113. In the fixed state (as described above) Figure 1A or Figure 1B As shown), the outer surface S2 of the intermediate member 120 is abutted by the spring piece 130, causing the inner surface S3 of the intermediate member 120 to abut against the inner stop surface S1, wherein the outer surface S2 and the inner surface S3 are two opposing surfaces of the intermediate member 120. Furthermore, Figure 2B The intermediary is depicted from another perspective, and Figure 2C This diagram illustrates the connection between the intermediary and the fiber optic assembly. Please also refer to... Figures 2A to 2CThe outer casing 110 also has a first guide post 114 extending from the inner stop surface S1 along the side wall 113 into the slot 112. At least one of the intermediary 120 and the optical fiber assembly 200 has a first guide groove (in this embodiment, the intermediary 120 has a first guide groove 121) to be adapted to the first guide groove 121 by means of the first guide post 114. During the insertion of the optical fiber assembly 200 and the intermediary 120 into the slot 112, the intermediary 120 and the optical fiber assembly 200 are guided and positioned in the slot 112. Here, the outer casing 110 also has a block 118 and a base plate 117. The block 118 has the aforementioned inner stop surface S1. The base plate 117 and the side walls 113 extend from the block 118 in the same direction and form the slot 112 with the inner stop surface S1. The shaft portion 111 for pivoting the spring piece 130 is located on the block 118.

[0024] Please refer to this again. Figure 1A , Figure 1B and Figure 2A In this embodiment, the fiber optic assembly 200 includes a fiber optic module 220 and a base 210, with the fiber optic module 220 disposed on the base 210. The housing 110 has a cutout 115 facing the photonic integrated circuit 300 and communicating with the slot 112. Figure 3A This is a side view of a co-packaged photonic fiber optic connector. Figure 3B This is a cross-sectional view of a co-packaged photonic fiber optic connector. Please also refer to... Figure 2A , Figure 3A and Figure 3B In this embodiment, the fiber optic module 220 includes an optical fiber (array) 221 and an optical element (array) 222, while the photonic integrated circuit 300 includes an optical waveguide 310. In the fixed state, the base 210 is located in the slot 112 and abuts against the inner stop surface S1. The fiber optic module 220 extends from the slot 112 to the hollow portion 115 to correspond to the photonic integrated circuit 300. Figure 3B As shown, the optical fiber assembly 200 and photonic integrated circuit 300, having completed optical coupling, can transmit optical signals, represented by the dashed arrows, from the optical waveguide 310 and optical element 222 to the optical fiber 221. In other words, the co-packaged photonic fiber connector 100 of this invention can efficiently and quickly complete the optical coupling operation between the optical fiber assembly 200 and the photonic integrated circuit 300.

[0025] Please refer to this again. Figure 1C , Figure 2A and Figure 3AIn this embodiment, the intermediary 120 also has a protruding step 122 located below the outer surface S2. In the fixed state, the base 210 of the fiber optic assembly 200 is abutted between the inner stop surface S1 and the protruding step 122. Here, the intermediary 120 has an inverted U-shaped structure with two opposing abutment ribs 123 and a channel 124 located between the two abutment ribs 123. The protruding step 122 extends from the end of the abutment rib 123. Therefore, in the fixed state, the channel 124 accommodates the fiber optic module 220, the abutment rib 123 contacts the side wall 113 of the housing 110, abuts against the inner stop surface S1, and is stacked on the base 210 of the fiber optic assembly 200. A portion of the protruding step 122 extends away from the channel 124 and fills the end recess 116 of the side wall 113, while another portion of the protruding step 122 abuts against the base 210. Furthermore... Figure 1B , Figure 1C As shown, the intermediate member 120 has a protrusion 125, which has the aforementioned outer surface S2 and forms a notch structure with the protruding step 122 for the spring piece 130 to be held.

[0026] Therefore, please refer to the following: Figure 2A , Figure 3A and Figure 3B Then one can from Figure 2A The structural features of the shown shrapnel 130 are known from this. Figure 3A and Figure 3B The force exerted by the spring piece 130 on the intermediary member 120 and its further effect on the optical fiber assembly 200 are described. In this embodiment, the spring piece 130 is T-shaped and has a horizontal segment T2 and a straight segment T1. The straight segment T1 intersects at the center of the horizontal segment T2. The end of the straight segment T1 away from the horizontal segment T2 has a pivot portion 131, which is pivotally wound around the shaft portion 111. The straight segment T1 is bent. In the fixed state, the straight segment T1 deforms and accumulates elastic force due to the bending interference with the top surface S4 of the intermediary member 120, so as to provide a first force F1 on the top surface S4 to press the intermediary member 120 into the slot 112 and press the optical fiber assembly 200 between the intermediary member 120 and the bottom of the slot 112 (i.e., the bottom plate 117 of the housing 110).

[0027] Furthermore, each of the opposite ends of the transverse segment T2 has a first hook 132. In the fixed state, the first hook 132 holds the intermediary 120 and the housing 110. The slot 112 has a first end E1 and a second end E2 opposite to each other, the shaft portion 111 is positioned at the first end E1, and the fiber optic assembly 200 and the intermediary 120 are adapted to move from the second end E2 to the first end E1 to be inserted into the slot 112, or to move from the first end E1 to the second end E2 to be removed from the slot 112. In the fixed state, the inner side of the notch of the first hook 132 abuts against the outer surface S2 of the intermediary 120, while the end of the first hook 132 simultaneously engages with the end notch 116 of the side wall 113 of the intermediary 120 and the outer shell 110. The first hook 132 deforms and accumulates elastic force due to the interference of the inner side of the notch with the outer surface S2 of the intermediary 120, thus providing a second force F2 to the outer surface S2. From the second end E2 towards the first end E1, the fiber optic assembly 200 is pressed between the intermediary 120 and the outer shell 110. Through the aforementioned first force F1 and second force F2 of the spring piece 130, the fiber optic assembly 200 is clamped and pressed between the intermediary 120 and the outer shell 110 while being engaged with the intermediary 120, thereby achieving the purpose of fixing it to the photonic integrated circuit 300. This embodiment improves the assembly accuracy of the mechanism and effectively simplifies the number of components by using an integrated shell 110 and a spring piece 130 with a single hook (first hook 132).

[0028] This embodiment is in Figure 3B A partial interference diagram of the spring 130 and the intermediary 120 is provided for reference. The part of the spring 130 interfering with the intermediary 120 is drawn with a dashed line to represent the amount of interference, which is also equivalent to the amount of deformation of the spring 130 at that point, so as to successfully provide the first force F1 and the second force F2.

[0029] Another example Figure 1C and Figure 2A As shown, the spring 130 in this embodiment also includes a pull handle 133, which extends from the center of the horizontal segment T2 and is relative to the straight segment T1, so that the user can pivot the spring 130 relative to the housing 110.

[0030] Figure 4A This is an exploded view of a co-packaged photonic fiber optic connector according to another embodiment of the present invention. Figure 4B Drawing from another perspective Figure 4A Exploded view. Figure 5A yes Figure 4A The above is an assembly diagram of a co-packaged photonic fiber optic connector. Please also refer to... Figure 4A , Figure 4B and Figure 5AUnlike the previous embodiments, the co-encapsulated photonic fiber optic connector 400 of this embodiment includes a housing 410, an intermediary 420, and a spring 430. The housing 410 includes a carrier P1 and a spacer P2. The spacer P2 is assembled to the carrier P1 and has a first guide post 414 and an inner stop surface S5. The carrier P1 has a shaft portion 111 and two side walls 413. In this embodiment, the carrier P1 also has a first arc-shaped rail 417A located on the side wall 413, while the spacer P2 has a second arc-shaped rail 417B. The spacer P2 is adapted to the first arc-shaped rail 417A via the second arc-shaped rail 417B and is assembled into the carrier P1, and stops at the end stop portion 418 of the first arc-shaped rail 417A. When the spring 430 holds and abuts against the outer shell 410 and the intermediate member 420 to achieve a fixed state, the spacer P2 abuts against the inside of the slot 412, and then the inner side surface S7 of the intermediate member 420 abuts against the inner stop surface S5 of the spacer P2, and the spring 430 provides the clamping force required for the above-mentioned components.

[0031] Furthermore, in this embodiment, the first arc-shaped rail 417A has a pair of arc-shaped inner walls AR1 extending from the end stop 418, and the second arc-shaped rail 417B has a pair of arc-shaped outer walls AR2 adapted to the arc-shaped inner walls AR1. Therefore, the spacer P2 can be inserted into the first arc-shaped rail 417A with the second arc-shaped rail 417B until it abuts and stops at the end stop 418. Moreover, there is a second guide groove 419 between the arc-shaped outer walls 417B, and the intermediate member 420 also has a second guide post 425 protruding from the inner side S7 and adapted to the second guide groove 419. Therefore, as... Figure 4A and Figure 4B As shown, the spacer P2 and the intermediary 120 have mutually compatible first guide posts 414, first guide grooves 421, second guide posts 425, and second guide grooves 419, so that the spacer P2 and the intermediary 420 can be smoothly assembled and positioned together. The intermediary 420 also has an inverted U-shaped structure with abutment ribs 423, and the abutment ribs 423 have the aforementioned first guide grooves 421.

[0032] Please refer to this again. Figure 4A and Figure 4B Compared to the aforementioned embodiments, the carrier P1 in this embodiment is essentially the structure of the outer shell 110 of the aforementioned embodiments after removing part of the block 118. The carrier P1 in this embodiment also has a side wall 413 and a bottom plate (such as the bottom plate 117 in the aforementioned embodiments) to form the required slot 412. The carrier P1 also has a hollow portion 415 so that after the spacer P2 moves into the slot 412, it is essentially the same as the outer shell 110 of the aforementioned embodiments, both having an inner stop surface S5 (inner stop surface S1 in the aforementioned embodiments) for the intermediate member 420 to be pressed by the elastic force of the spring piece 430.

[0033] Figure 5Ayes Figure 4A A schematic diagram of the assembly of a co-packaged photonic fiber optic connector. Figure 5B yes Figure 5A A partial schematic diagram is provided, omitting the spring piece 430 to facilitate identification of the correspondence between the intermediate component 420 and the housing 410 at the second end E4 of the slot 412. Please also refer to 5A and... Figure 5B In this embodiment, the spring piece 430 is also T-shaped, having a horizontal segment T3 and a straight segment T1. The straight segment T1 intersects at the center of the horizontal segment T3. The end of the straight segment T1 away from the horizontal segment T3 has a pivot portion 131, which can pivotally wrap around the shaft portion 111. The straight segment T1 is bent. In the fixed state, the straight segment T1 bends and interferes with the deformation of the top surface S8 of the intermediate member 420 and accumulates elastic force to provide a first force (such as the first force F1 in the aforementioned embodiment) to the top surface S8, thereby pressing the intermediate member 420 into the slot 412 and pressing the optical fiber assembly 200 between the intermediate member 420 and the bottom of the slot 412.

[0034] Furthermore, each end of the horizontal segment T3 has a first hook 432 and a second hook 434. In the fixed state, the first hook 432 holds the end notch 416 of the carrier P1 of the outer shell 410, and the second hook 434 abuts against the post 422 of the intermediate member 420. The post 422 protrudes beyond the first guide groove 421 of the abutment rib 423. The slot 412 has a first end E3 and a second end E4 opposite to each other. The shaft portion 111 is located at the first end E3. The fiber optic assembly 200 and the intermediate member 420 are adapted to move from the second end E4 to the first end E3 to insert into the slot 412, or from the first end E3 to the second end E4 to remove from the slot 412. In the fixed state, the second hook 434 abuts against the outer surface S6 of the intermediary member 420, and the second hook 434 interferes with the outer surface S6 of the intermediary member 420 to deform and accumulate elastic force, so as to provide a second force (as described above, the second force F2) to the outer surface S6, pressing the optical fiber assembly 200 between the intermediary member 420 and the outer shell 410 from the second end E4 toward the first end E3. Similarly, the spring 430 in this embodiment also has a pull handle 433 located at the center of the transverse segment T3, so as to facilitate the user to operate the spring 430 to pivot relative to the outer shell 410.

[0035] As mentioned above Figures 1A to 3BCompared to the illustrated embodiment, this embodiment is provided based on assembly requirements. In this embodiment, the housing 410 is further divided into a carrier P1 and a spacer P2, allowing the operator to first assemble the spacer P2, the intermediary 420, and the fiber optic assembly 200, and then insert the assembled three components into the carrier P1 with slot 412. It should be noted that the co-encapsulated photonic fiber optic connector 400 of this invention has external dimensions (length, width, height) of approximately 18mm, 18mm, and 6.5mm, which is difficult for operators to handle and hinders their work efficiency. Therefore, by redesigning the structure of the housing 410 in this embodiment, its assembly efficiency is significantly improved.

[0036] Furthermore, in this embodiment, the first hook 432 and the second hook 434 respectively hold and abut against the corresponding outer shell 410 and the intermediate member 420, compared to the aforementioned Figures 1A to 3B The single hook shown (first hook 132) in this embodiment focuses on the dimensional correspondence between the intermediate member 420 and the outer shell 410 (especially its structure at the side wall 413). That is, it simultaneously considers that the spring piece 430 needs to meet the holding and pressing force of both the outer shell 410 and the intermediate member 420. Therefore, a forked hook (first hook 432, second hook 434) is adopted so that the elasticity can be adjusted in a timely manner by changing the degree of bending of the hook to meet the requirements.

[0037] Figure 6A A schematic diagram of an optical fiber assembly according to another embodiment of the present invention. Figure 6B yes Figure 6A This is a schematic diagram showing the assembly of fiber optic components with intermediate and spacer parts. Please also refer to... Figure 6A and Figure 6B Unlike the previous embodiments, in this embodiment, the fiber optic assembly 500 has a fiber optic module 220 disposed on a base 510, and the base 510 has wings protruding from opposite sides of the fiber optic module 220, with grooves 511 present on these wings. Therefore, as... Figure 6B As shown, when the fiber optic assembly 500 is covered by the intermediary 420 and is about to be assembled with the spacer P2, the trench 511 will combine with the first guide groove 421 of the intermediary 420 to form a new guide groove CH, which is adapted to the first guide post 414 of the spacer P2.

[0038] In summary, in the above embodiments of this utility model, the co-encapsulated photonic fiber optic connector is assembled to the housing via a spring clip and can pivot relative to the housing. After the fiber optic assembly is inserted into the slot and the intermediate component is also inserted into the slot to cover the fiber optic assembly, the spring clip can be pivoted and held in at least one of the housing and the intermediate component, so that the elastic force of the spring clip can press against the fiber optic assembly through the intermediate component, thus fixing the fiber optic assembly in the slot of the housing.

[0039] In one embodiment, the housing is a one-piece structure, meaning it can be manufactured using a single process, resulting in better structural precision that facilitates the support and fixation of the fiber optic assembly. In another embodiment, the housing consists of a carrier and spacers, wherein the spacers have inner stop surfaces for the intermediary to abut against. This allows the fiber optic assembly to be pre-assembled with the intermediary and spacers before being inserted into the slots in the housing, improving the convenience of the assembly process.

[0040] In one embodiment, the end of the spring piece away from its pivot point with the housing has a single hook to simultaneously engage with the sidewalls of both the intermediary and the housing. The intermediary also allows a portion of its protruding step to abut against the end recess of the sidewall, enabling the single hook to engage the protruding step while simultaneously applying pressure to the sidewall of the housing, achieving a better and more secure fixation. In another embodiment, the end of the spring piece away from its pivot point with the housing has two hooks to provide both engagement and abutment against the sidewalls of the intermediary and the housing, respectively. This allows for the provision of hooks with different elastic properties depending on the size of the intermediary and the housing and the fixation requirements, improving design convenience.

[0041] In addition to enabling rapid assembly and disassembly of fiber optic assemblies and photonic integrated circuits through the cooperation of spring contacts, housings, and intermediaries, this approach also allows the spring contacts pivoted on the housing to abut against the intermediaries, thus effectively protecting the fiber optic assemblies with the intermediaries. This provides a stable assembly mechanism for the fiber optic assemblies and photonic integrated circuits and extends the service life of the fiber optic assemblies.
