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 discloses a co-packaged photonic fiber optic connector, configured on a photonic integrated circuit to receive fiber optic assemblies and optically couple the fiber optic assemblies to the photonic integrated circuit. The co-packaged photonic fiber optic connector includes a housing, an interposer, and a spring. The housing is mounted on the photonic integrated circuit and has a slot. The interposer is adapted to be inserted into or removed from the slot and has a shaft portion. A portion of the spring is pivotally connected to the shaft portion to pivot relative to the interposer. In the fixed state, the fiber optic assembly is inserted into the slot, the interposer is inserted into the slot and covers the fiber optic assembly, and another portion of the spring is fastened to the housing to assemble the interposer and the housing together. The spring presses the fiber optic assembly through the interposer to secure the fiber optic assembly in the slot of the housing.

[0005] Based on the above, the co-packaged photonic fiber optic connector utilizes a mechanism where spring contacts are assembled to an intermediary and pivot relative to the housing. After the fiber optic assembly is inserted into the slot, and the intermediary is also inserted into the slot to cover the fiber optic assembly, the spring contacts can be pivoted and secured to the housing. In other words, the spring contacts hold the housing and intermediary together, and the elasticity of the spring contacts, through the intermediary, presses against the fiber optic assembly, fixing it in the slot within the housing. This not only allows for quick assembly and disassembly of the fiber optic assembly and photonic integrated circuit through the interaction of the spring contacts, housing, and intermediary, but also provides effective bonding force by having the spring contacts, pivoted on the intermediary, hook onto the housing after the intermediary is inserted into the slot. More importantly, the spring contacts only engage with the housing and intermediary, without making direct structural contact with the fiber optic assembly. Therefore, the intermediary effectively protects the fiber optic assembly, providing a stable assembly mechanism for the fiber optic assembly and photonic integrated circuit and extending the lifespan of the fiber optic assembly.

Detailed Implementation

[0017] 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 This describes another state of the co-packaged photonic fiber optic connector. Cartesian coordinates (XYZ) are provided here for ease of component description. Please also refer to... Figures 1A to 1C In this embodiment, a co-packaged photonic fiber optic connector 100 is disposed on a photonic integrated circuit 300 to receive a fiber optic assembly 200 and to optically couple the fiber optic assembly 200 to the photonic integrated circuit 300. The co-packaged photonic fiber optic connector 100 includes a housing 110, an intermediary 120, and a spring 130. After the intermediary 120 and the fiber optic assembly 200 are assembled into the housing 110, the spring 130 holds the housing 110 in place, thereby combining the housing 110 and the intermediary 120 together and pressing the fiber optic assembly 200 therebetween.

[0018] Here, the photonic integrated circuit (PIC) 300 utilizes semiconductor manufacturing processes to directly integrate optical components such as modulators, switches, and beam splitters into a single 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 achieved through optical waveguides. Through these miniaturized and highly stable integrated optical elements, optoelectronic communication systems can play an increasingly important role and function.

[0019] Figure 2 This is an exploded view of a co-packaged photonic fiber optic connector. Please also refer to... Figure 1A and Figure 2 Furthermore, the housing 110 is mounted on the photonic integrated circuit 300 and has a slot 112. An intermediary 120 is adapted to be inserted into or removed from the slot 112, and the intermediary 120 has a shaft portion 121. A portion of a spring 130 is pivotally connected to the shaft portion 121 to pivot relative to the intermediary 120. In the fixed state, the fiber optic assembly 200 is inserted into the slot 112, the intermediary 120 is inserted into the slot 112 and covers the fiber optic assembly 200, and another portion of the spring 130 is engaged with a holding portion 118 of the housing 110 to assemble the intermediary 120 with the housing 110. The spring 130 presses the fiber optic assembly 200 through the intermediary 120 to secure the fiber optic assembly 200 in the slot 112 of the housing 110. In this embodiment, taking the housing 110 as an example located on the XY plane, the intermediary 120 and the fiber optic assembly 200 move in the positive Y-axis direction to insert into the slot 112, and move in the negative Y-axis direction to move out of the slot 112.

[0020] In detail, the outer shell 110 of this embodiment also has a block 111 and a base plate 117. The block 111 has an inner stop surface S1. The base plate 117 and the two side walls 113 extend from the block 111 in the same direction (towards the negative Y-axis) and form a slot 112 with the inner stop surface S1.

[0021] Figure 3 and Figure 4A The following diagrams illustrate some components of the co-packaged photonic fiber optic connector from different perspectives. Please refer to the following for further information. Figure 1A , Figure 2 and Figure 3The outer casing 110 has two side walls 113 forming a slot 112 and an inner stop surface S1. The side walls 113 are opposite to each other, and the inner stop surface S1 is adjacent to the side walls 113. In the fixed state, the inner surface S3 of the intermediary member 120 abuts against the inner stop surface S1. Further, the slot 112 of this embodiment has a first end E1 and a second end E2 opposite to each other. The fiber optic assembly 200 and the intermediary member 120 are adapted to move from the second end E2 to the first end E1 to insert into the slot 112, or to move from the first end E1 to the second end E2 to remove from the slot 112. In the fixed state, the shaft portion 121 of the intermediary member 120 is located at the second end E2.

[0022] Figure 4B This illustration presents the intermediary document from another perspective. Please also refer to... Figure 2 , Figure 4A and Figure 4B ,in Figure 4A This can be considered as the state after the intermediary 120 and the fiber optic assembly 200 have been inserted into the slot 112 (the housing 110 is omitted here), and Figure 4B Is as Figure 4A Further omissions are made regarding the fiber optic assembly 200. In this embodiment, the intermediary 120 has an inverted U-shaped structure and includes two abutment ribs 122 and a channel 124 located between the two abutment ribs 122. Correspondingly, 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. Figure 4A As shown, in the fixed state, the fiber optic assembly 200 is housed in the channel 124, and the abutment block 123 of the intermediary 120 abuts against the base 210. Corresponding to... Figure 1A or Figure 2 It can be seen that when the intermediary 120 holds the holding portion 118 of the outer shell 110 by the spring piece 130, it is equivalent to providing a force to the intermediary 120 in the positive Y-axis direction, so that the abutment block 123 is tightly pressed against the base 210, and the inner side surface S3 of the intermediary 120 is tightly pressed against the inner stop surface S1 of the outer shell 110, thus smoothly clamping the base 210 of the fiber optic assembly 200 between the abutment block 123 and the inner stop surface S1. Here, the abutment block 123 can be regarded as extending from the structure of the abutment rib 122 and located on the same side of the intermediary 120 as the shaft portion 121, and arranged vertically along the Z-axis, as shown. Figure 1A As shown.

[0023] Furthermore, please refer to [the following]: Figure 2 , Figure 3 and Figure 4A The housing 110 also has a first guide post 114 extending from the inner stop surface S1 along the side wall 113 into the slot 112, and at least one of the intermediary 120 and the fiber optic assembly 200 has a first guide groove for fitting with the first guide post 114. In this embodiment, the intermediary 120 has a V-shaped groove 125 at its abutment rib 122 (e.g., Figure 4B As shown), the fiber optic assembly 200 is paired with a V-groove 211 on the wing of its base 210 (as shown). Figure 2 As shown), together they form the first guide groove CH of this invention. However, this invention is not limited to this; in other embodiments not shown, the first guide post 114 can be appropriately adjusted so that one of the intermediate component 120 or the base 210 of the fiber optic assembly 200 has the aforementioned first guide groove. In other words, any method that allows the fiber optic assembly 200 and the intermediate component 120 to smoothly move into the slot 112 of the housing 110 and achieve the desired guiding and positioning effect is applicable to this invention.

[0024] Please refer to this again. Figure 2 In this embodiment, the spring 130 is T-shaped, having a horizontal segment T2 and a vertical segment T1. The vertical segment T1 intersects at the center of the horizontal segment T2. The end of the vertical segment T1 away from the horizontal segment T2 has a pivot portion 131, which is pivotally wound around the shaft portion 121. Each of the opposite ends of the horizontal segment T2 has a hook 132. In the fixed state, the hook 132 holds the outer structure of the outer shell 110 facing away from the slot 112 (i.e., the holding portion 118). 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 vertical segment T1. The pull handle 133 facilitates the user's grip to operate the spring 130 to pivot relative to the intermediate member 120, making it easy to hold it to or release it from the holding portion 118.

[0025] Figure 5A and Figure 5B These are cross-sectional views of the co-packaged photonic fiber optic connector at different levels. Please also refer to... Figure 1B , Figure 5A and Figure 5B In this embodiment, the outer casing 110 also has a cutout portion 115 facing the photonic integrated circuit 300 and communicating with the slot 112. The fiber optic module 220 of this embodiment 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 cutout portion 115 to correspond to the photonic integrated circuit 300, and... Figure 3 As shown, the optical fiber assembly 200 and photonic integrated circuit 300, which complete the optical coupling, can transmit the optical signal, represented by the dashed arrow, from the optical waveguide 310 and optical element 222 to the optical fiber 221.

[0026] In order to achieve the aforementioned fixed state smoothly, the spring piece 130 in this embodiment is in a bent original (unforced) state in its straight section T1. Therefore, in the fixed state, the straight section T1 will be deformed and accumulate elastic force due to the bending interference of the top surface S2 of the intermediate member 120, so as to provide a first force F1 to the top surface S2 and press the intermediate member 120 into the slot 112, and also press the optical fiber assembly 200 covered by the intermediate member 120, so that the optical fiber assembly 200 is actually fixed between the intermediate member 120 and the bottom of the slot 112 (i.e., the aforementioned bottom plate 117). Furthermore, in the fixed state, the hook 132 of the spring tab 130 also provides a second force F2 to the holding portion 118 of the housing 110. This is equivalent to the pivot portion 131 of the spring tab 130 providing a reverse force to the intermediary member 120, which, together with the second force F2, abuts the intermediary member 120 and the housing 110 together along the Y-axis, thereby pressing the fiber optic assembly 200 between the intermediary member 120 and the housing 110. Accordingly, by applying force to the housing 110 and the intermediary member 120 by the spring tab 130, the fiber optic assembly 200 can be effectively fixed in the slot 112. Simply put, the spring tab 130 can be regarded as a fastener structure that combines the intermediary member 120 and the housing 130.

[0027] like Figure 5B As shown by the dashed line in the enlarged partial view, the spring piece 130 interferes with the top surface S2 of the intermediate member 120 at its straight section T1, thereby causing the spring piece 130 to deform and accumulate elastic force to form the first applied force F1.

[0028] Figure 5C yes Figure 1A A partial view of the co-packaged photonic fiber optic connector. Please also refer to... Figure 5B and Figure 5C It should also be mentioned that the intermediary member 120 in this embodiment also has a stop protrusion 122a that extends from the abutment rib 122 away from the V-shaped groove 125 and protrudes outward from the outside of the intermediary member 120. The V-shaped groove 125 of the first guide groove CH is located between the channel 124 and the stop protrusion 122a. The side wall 113 of the outer shell 110 has an end notch 116 at the second end E2 of the slot 112, so that when the intermediary member 120 is inserted into the slot 112 in the fixed state, the stop protrusion 122a fills the end notch 116, thereby confining the intermediary member 120 in the slot 112 and preventing the intermediary member 120 from flipping out of the slot 112 due to the elastic force of the spring piece 130. Figure 5B As shown, in addition to providing a force along the Y-axis to the housing 110, the hook 132 also generates a third force F3 on the housing 110 due to the inclined surface of the fastening portion 118. In this way, the second force F2 and the third force F3 generate a torque through the shaft portion 121, driving the intermediate member 120 along... Figure 5B The dashed arrow shown is flipped and pulled out of slot 112. Therefore, this embodiment achieves this through... Figure 5C The stop protrusion 122a shown interferes with the side wall 113 at the end recess 116, thereby preventing the aforementioned intermediate member 120 from being pulled out of the slot 112 by the spring piece 130.

[0029] Figure 6 This is a schematic diagram of a co-encapsulated photonic fiber optic connector according to another embodiment of the present invention. Figure 7 yes Figure 6 An exploded view of the co-packaged photonic fiber optic connector. Please also refer to... Figure 6 and Figure 7 It should be noted that the structural or component features indicated by the same symbols in this embodiment and the previous embodiments have been mentioned in the previous embodiments, so they will not be repeated here.

[0030] The difference from the previous embodiment is that the outer shell 410 of this embodiment is composed of a carrier P1 and a spacer P2, wherein the spacer P2 is assembled to the carrier P1, and the spacer P2 has a first guide post 114 and an inner stop surface S1. The carrier P1 has a slot 112 and two side walls 113. The slot 112 has a first end E3 and a second end E4 that are opposite to each other. The spacer P2, the optical fiber assembly 200 and the intermediary 420 are respectively moved from the second end E2 to the first end E1 to be inserted into the slot 112.

[0031] Furthermore, the carrier P1 also has a first arc-shaped rail 411A located on the side wall 113, while the spacer P2 has a second arc-shaped rail 411B. The spacer P2 is fitted into the carrier P1 by adapting the second arc-shaped rail 411B to the first arc-shaped rail 411A, and stops at the end stop portion 412 of the first arc-shaped rail 411A. In this embodiment, the first arc-shaped rail 411A has a pair of arc-shaped inner walls AR1 extending from the end stop portion 412 along the side wall 113, and the second arc-shaped rail 411B has a pair of arc-shaped outer walls AR2, adapted to the arc-shaped inner walls AR1 so that the second arc-shaped rail 411B can be substantially inserted into the space between the arc-shaped inner walls AR1. In addition, there is a second guide groove 419 between the outer arc wall AR2, and the intermediate member 420 also has a second guide post 421, which protrudes from the inner side S3 and is adapted to the second guide groove 419. The intermediate member 420 is adapted to the second guide groove 419 through the second guide post 421, and guides and positions itself with the spacer P2 during the process of the intermediate member 420 being inserted into the slot 112.

[0032] As mentioned above Figures 1A to 5BCompared 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 112. 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.

[0033] In summary, in the above embodiments of this utility model, the co-encapsulated photonic fiber optic connector uses a spring-loaded mechanism to assemble the fiber optic component into the housing and pivot it relative to the housing. After the fiber optic component is inserted into the slot and an intermediary is also inserted into the slot to cover the fiber optic component, one end of the spring-loaded connector can be held and pivotally connected to the shaft of the intermediary, while the other end of the spring-loaded connector is held to the external structure of the housing facing away from the slot. In this way, the spring-loaded connector can hold and combine the intermediary and the housing together, and further fix the fiber optic component in the slot and press it between the intermediary and the housing.

[0034] In one embodiment, the housing is a single-piece structure, meaning that the block and sidewalls of the same structure can be manufactured through a single process, resulting in better structural precision that facilitates the support and fixation of the fiber optic assembly. In another embodiment, the housing is assembled from separate carriers and spacers, wherein the carrier has a slot, and the spacer has an inner stop surface for the intermediary to abut. This allows the fiber optic assembly to be assembled with the intermediary and spacers first, and then inserted into the slot of the housing. By reconfiguring the structure of the housing, the assembly sequence can be changed, improving the convenience and efficiency of the assembly process.

[0035] Based on the above, the co-packaged photonic fiber optic connector, in addition to enabling rapid assembly and disassembly of fiber optic assemblies and photonic integrated circuits through the interaction of the spring contacts, housing, and intermediary, also provides effective bonding force by having the spring contacts pivotally mounted on the intermediary hook onto the housing after the intermediary is inserted into the slot. More importantly, the spring contacts engage and abut against the housing and intermediary, without making direct structural contact with the fiber optic assembly. Therefore, it effectively protects the fiber optic assembly with the intermediary, thereby providing a stable assembly mechanism for the fiber optic assembly and photonic integrated circuits and extending the service life of the fiber optic assembly.
