[0061] In optical communication technology, optical signals are used as carriers of information for high-speed, long-term, and reliable information transmission. As a core component in the field of optical communication, the coupling effect between the optical components and the transmission path (optical fiber) in the optical module greatly affects the intensity and quality of the optical signal, thus becoming one of the key factors affecting information transmission.

[0062] As the core device in optical fiber transmission, the various indicators of the optical module determine the overall performance of the transmission. The optical module is the carrier of transmission between the switch and the device, and its main function is to realize the conversion between electrical signals and optical signals. Its basic structure consists of two parts: "optical transmitting component and its driving circuit" and "optical receiving component and its receiving circuit".

[0063] Generally, an optical module contains two channels, namely a transmitting channel and a receiving channel.

[0064] Among them, the composition and working principle of the transmission channel are as follows:

[0065] The transmission channel of the optical module is composed of an electrical signal input interface, a laser driving circuit, an impedance matching circuit, and a laser component. Its working principle is that the electrical interface input of the transmission channel completes the coupling of the electrical signal through the electrical interface circuit, and then passes through the laser driving circuit in the transmission channel for modulation, and then performs impedance matching through the impedance matching circuit to complete the modulation and driving of the signal, and finally sends it to the laser to convert the electrical signal into an optical signal, and transmits the optical signal through the optical fiber.

[0066] The composition and working principle of the receiving channel are as follows:

[0067] The receiving channel of the optical module consists of a light detector assembly (composed of a photodetection diode and a transimpedance amplifier), an impedance matching circuit, a limiting amplifier circuit, and an electrical signal output interface circuit.

[0068] Its working principle is that the photodetection diode converts the collected light signal into an electrical signal in direct proportion, the transimpedance amplifier converts the electrical signal into a voltage signal, and amplifies the converted voltage signal to the required amplitude, and transmits it to the limiting amplifier circuit through the impedance matching circuit to complete the signal amplification and shaping again, thereby improving the signal-to-noise ratio and reducing the bit error rate. Finally, the electrical interface circuit completes the signal output.

[0069] There are two methods for achieving optical path coupling between optical components and transmission optical fibers in optical modules: active coupling and passive coupling.

[0070] The process of the active coupling method is: fix the laser as the light source on the PCB board, then control the laser to emit light, use the coupler to adjust the spatial position of the optical lens module used as a device to change the optical transmission path, and detect the light intensity coupled into the optical fiber through the module. When the light intensity emitted by the optical fiber reaches the maximum value, the lens position at this time is determined to be the optimal coupling position.

[0071] The process of the passive coupling method is: first fix the laser, then use two cameras to photograph the laser and the optical lens module respectively, transmit the images to the PC, adjust the position of the lens, and when the centers of the two images coincide, determine that the lens position at this time is the optimal coupling position.

[0072] Laser is an important component of optical devices (optical signal receiving and transmitting components). The laser is composed of multiple tube legs. In the processing of optical devices, laser coupling is an important link, and the stability and angle control of the laser during coupling directly determine the quality of the product.

[0073] In the first aspect, combined Figures 1 to 10 As shown, an embodiment of the present disclosure provides a device for coupling optical devices, which includes a Z-axis motion mechanism 3, a clamping mechanism 1 and a control module. The clamping mechanism 1 includes a base 11, a cantilever frame 12, a picking portion 13 and a pressure sensor 14.

[0074] The Z-axis motion mechanism 3 , the pressure sensor 14 and the pickup portion 13 are all electrically connected to the control module.

[0075] The Z-axis motion mechanism 3 is a mechanism capable of performing linear motion in the Z-axis direction, and is generally composed of a guide rail, a slider, and a transmission system. Among them, the guide rail is a basic component that supports and guides the movement of the slider, and the slider is a component responsible for bearing and transmitting the load and performing linear motion on the guide rail. The transmission system is used to drive the slider to perform linear motion on the guide rail, and common transmission systems include screw transmission and gear transmission. In the present application, the specific structural form of the Z-axis motion mechanism 3 can be set according to actual needs, and is not limited here.

[0076] Combination Figure 1 As shown, the base 11 is L-shaped, and mounting holes 111 are respectively formed on the four corners of the side wall of the base 11. Bolts or screws pass through the mounting holes 111 to fix one end of the base 11 on the Z-axis motion mechanism 3, and the base 11 is driven to move through the Z-axis motion mechanism 3.

[0077] It should be noted that the shape of the base 11 includes but is not limited to the above-mentioned forms.

[0078] Combination Figure 1 and Figure 2 As shown, one end of the cantilever frame 12 is fixedly connected to the other end of the base 11 by a fastener;

[0079] Combination Figure 3 and Figure 4 As shown, the picking portion 13 is fixedly disposed at the lower portion of the cantilever frame 12 away from the base 11. Specifically, the picking portion 13 is fixedly connected to the cantilever frame 12 by fasteners such as bolts. The picking portion 13 is configured to pick up the optical fiber array assembly 2, and driven by the Z-axis motion mechanism 3, the picking portion 13 drives the optical fiber array assembly 2 to move toward or away from the optical chip.

[0080] When the optical fiber array assembly 2 moves toward the direction approaching the optical chip, it is convenient for the optical fiber array assembly 2 to contact the optical chip; when the optical fiber array assembly 2 moves toward the direction away from the optical chip, it is convenient to adjust the distance between the optical fiber array assembly 2 and the optical chip through the Z-axis motion mechanism 3.

[0081] Combination Figure 5 and Figure 7 As shown, the pressure sensor 14 is fixedly arranged at the end of the cantilever frame 12 close to the base 11. Specifically, a connecting portion 122 is formed at the upper portion of the cantilever frame 12 close to the base 11, and the cantilever frame 12 is fixedly connected to the base 11 through the connecting portion 122; the pressure sensor 14 is arranged in the transverse direction, and the bottom of the pressure sensor 14 is fixed to the side of the connecting portion 122 away from the base 11 through fasteners such as bolts;

[0082] A pressure transmission part 121 is formed at the upper end of the cantilever frame 12, and the pressure transmission part 121 is located between the base 11 and the picking part 13. The pressure transmission part 121 abuts against the pressure sensor 14, and the pressure sensor 14 is located between the pressure transmission part 121 and the connecting part 122. In the present application, the pressure transmission part 121 plays a role in transmitting pressure. Since the end of the cantilever frame 12 is fixed on the base 11, when the lower part of the cantilever frame 12 away from the base 11 is subjected to an upward force, the cantilever frame 12 will be deformed and transmitted to the pressure sensor 14 through the pressure transmission part 121.

[0083] The pressure sensor 14 is electrically connected to the control module. The pressure sensor 14 detects pressure and transmits a pressure signal to the control module. The control module receives the pressure signal transmitted by the pressure sensor 14 and controls the movement of the Z-axis motion mechanism 3 .

[0084] In the initial state, the control module controls the Z-axis motion mechanism 3 to move so that the optical fiber array assembly 2 moves in a direction close to the optical chip. When the optical fiber array assembly 2 is in contact with the optical chip, the distance between the optical fiber array assembly 2 and the optical chip is 0, and contact pressure is generated between the optical fiber array assembly 2 and the optical chip. The contact pressure between the optical fiber array assembly 2 and the optical chip is sequentially transmitted to the pressure sensor 14 through the picking part 13, the cantilever frame 12 and the pressure transmission part 121; the pressure sensor 14 transmits the detected pressure signal to the control module, and the control module controls the Z-axis motion mechanism 3 to move according to the pressure signal, so that the optical fiber array assembly 2 moves in a direction away from the optical chip. When the distance between the optical fiber array assembly 2 and the optical chip reaches the set value, the control module controls the Z-axis motion mechanism 3 to stop moving.

[0085] Specifically, the device for coupling optical devices includes a Z-axis motion mechanism 3, a clamping mechanism 1 and a control module. The clamping mechanism 1 includes a base 11, a cantilever frame 12, a pick-up portion 13 and a pressure sensor 14. One end of the base 11 is fixed on the Z-axis motion mechanism 3, and the other end of the base 11 is fixedly connected to the cantilever frame 12. The pick-up portion 13 is fixed to the lower part of the cantilever frame 12. The pick-up portion 13 is used to pick up the optical fiber array assembly 2. The upper end of the cantilever frame 12 is formed with a pressure transmission portion 121, and the pressure transmission portion 121 is located between the base 11 and the pick-up portion 13. The contact pressure between the optical component 2 and the optical chip is transmitted to the pressure sensor 14 through the picking part 13, the cantilever frame 12 and the pressure transmission part 121 in turn. The control module controls the movement of the Z-axis motion mechanism 3 to drive the picking part 13 to absorb the optical fiber array component 2 to move towards or away from the optical chip. The contact between the optical fiber array component 2 and the optical chip is fed back through the pressure sensor 14 to achieve the precise contact position between the optical fiber array component 2 and the optical chip, reduce the contact error, and is beneficial to protecting the optical chip. At the same time, it provides a basis for accurately adjusting the distance between the optical device and the optical chip.

[0086] Combination Figure 5 and Figure 6 As shown, in some embodiments of the present application, the picking portion 13 includes a clamping portion 131 and a clamping driving portion 132 .

[0087] The clamping portion 131 is used to clamp or pick up the optical fiber array assembly 2;

[0089] Specifically, by providing the clamping portion 131 and the clamping driving portion 132 , the picking force of the optical fiber array assembly 2 can be precisely controlled, which is beneficial to ensuring the consistency of the picking force.

[0091] The main body 1311 is fixedly connected to the clamping drive part 132;

[0092] The first clamping jaw 1312 and the second clamping jaw 1313 are distributed on both sides of the main body 1311, and the first clamping jaw 1312 and the second clamping jaw 1313 are arranged opposite to each other;

[0093] The first clamping jaw 1312 and / or the second clamping jaw 1313 are movably connected to the clamping driving portion 132 , and the clamping driving portion 132 drives the first clamping jaw 1312 and / or the second clamping jaw 1313 to move toward or away from the main body 1311 to clamp or release the optical fiber array assembly 2 .

[0094] Combination Fig. 9 and Fig.10 As shown, in some embodiments of the present application, a clamping groove 1314 is formed between the bottom surface of the main body 1311 and the first clamping jaw 1312 and the second clamping jaw 1313, and the clamping groove 1314 is configured to place the optical fiber array assembly 2, and the depth of the clamping groove 1314 is less than or equal to the thickness of the optical fiber array assembly 2, so that when the first clamping jaw 1312 and the second clamping jaw 1313 clamp the optical fiber array assembly 2, the optical fiber array assembly 2 is in the clamping groove 1314, and since the depth of the clamping groove 1314 is less than or equal to the thickness of the optical fiber array assembly 2, this facilitates the contact between the optical fiber array assembly 2 and the optical chip.

[0095] In some embodiments of the present application, a suction channel 1315 is formed inside the main body 1311 , the suction channel 1315 is communicated with the clamping groove 1314 , and the suction channel 1315 is configured to be used for negative pressure suction of the optical fiber array assembly 2 .

[0096] Specifically, by setting up the suction channel 1315, the suction channel 1315 is connected with the clamping groove 1314, and the optical fiber array assembly 2 can be sucked into the clamping groove 1314 by evacuating the suction channel 1315 to form a negative pressure, and the optical fiber array assembly 2 is clamped by the first clamp 1312 and the second clamp 1313 to prevent the optical fiber array assembly 2 from falling.

[0097] Exemplarily, the suction channel 1315 is a cylindrical cavity structure.

The air pipe connector 1316 is suitable for connecting a vacuum extraction device to facilitate vacuum extraction of the suction channel 1315 .

[0099] Exemplarily, the vacuum pump may be a vacuum pump or an air pump.

[0100] In some embodiments of the present application, the clamping driving portion 132 includes a cylinder, and the first clamping jaw 1312 and / or the second clamping jaw 1313 are connected to a piston rod of the cylinder.

[0101] Specifically, the clamping driving part 132 includes a cylinder, and the first clamping jaw 1312 and / or the second clamping jaw 1313 are connected to the piston rod of the cylinder, so that the cylinder drives the piston rod to drive the first clamping jaw 1312 and / or the second clamping jaw 1313 to move.

[0102] In some embodiments of the present application, the first clamping jaw 1312 or the second clamping jaw 1313 is fixedly connected to the main body 1311 .

[0103] Specifically, by fixedly connecting the first clamping jaw 1312 or the second clamping jaw 1313 to the main body 1311, that is, the first clamping jaw 1312 or the second clamping jaw 1313 and the main body 1311 are an integrated structure, it is easy to process on the one hand, and easy to control the opening or closing of the clamping jaw on the other hand.

[0104] Exemplary, combined Fig.10 As shown, the first clamping jaw 1312 and the main body 1311 are an integrated structure, and the second clamping jaw 1313 is movable.

[0105] In the present application, when the air pipe connector 1316 is connected to a vacuum pump, the suction channel 1315 can be vacuumed, so that the optical fiber array assembly 2 can be adsorbed. In conjunction with the first clamp 1312 and the second clamp 1313, the angle of the optical fiber array assembly 2 can be corrected, so that the angle of the optical fiber array assembly 2 is adapted to the angle of the optical chip to be contacted.

[0106] In some embodiments of the present application, the pressure transmission part 121 includes a bracket 1211 and a transmission member 1212 .

[0107] The bracket 1211 is fixedly disposed on the upper end of the cantilever frame 12. Specifically, the bracket 1211 and the cantilever frame 12 may be an integrated structure or a split structure.

[0108] One end of the transmission member 1212 is clamped and fixed on the bracket 1211 , and the other end of the transmission member 1212 is in contact with the pressure sensor 14 .

[0109] In certain embodiments of the present application, the other end of the transmission member 1212 is connected to the pressure sensor 14 via threads.

[0110] Specifically, when the Z-axis motion mechanism 3 drives the base 11 to move toward the optical chip, when the optical fiber array assembly 2 touches the optical chip, the optical fiber array assembly 2 is subjected to resistance, and contact pressure is generated between the optical fiber array assembly 2 and the optical chip, which is transmitted to the cantilever frame 12 through the picking portion 13. The cantilever frame 12 is subjected to force, and the cantilever frame 12 will have a slight deformation. The cantilever frame 12 acts as a lever, and a transmission member 1212 is fixed on the cantilever frame 12. The transmission member 1212 is transmitted to the pressure sensor 14, thereby amplifying the slight deformation. The pressure sensor 14 transmits the pressure signal to the control module. The control module determines that the optical fiber array assembly 2 is in contact with the optical chip based on the pressure signal, and controls the movement of the Z-axis motion mechanism 3 to maintain a micrometer-level spacing between the optical fiber array assembly 2 and the optical chip.

[0111] The present application avoids errors caused by vision or camera shooting, and on the basis that the contact time distance between the optical fiber array assembly 2 and the optical chip is 0, the optical fiber array assembly 2 is driven to move by the Z-axis motion mechanism 3, so that the spacing between the optical fiber array assembly 2 and the optical chip can reach the micron level.

[0112] In some embodiments of the present application, the transfer member 1212 has a cylindrical structure to facilitate stress transmission.

[0113] In the second aspect, an embodiment of the present disclosure provides a device for coupling optical devices, wherein the device for coupling optical devices includes a Z-axis motion mechanism 3, a clamping mechanism 1 and a control module, wherein the clamping mechanism 1 includes a base 11, a cantilever frame 12, a picking portion 13 and a pressure sensor 14.

[0114] One end of the base 11 is suitable for being fixed on the Z-axis motion mechanism 3;

[0115] The cantilever frame 12 is fixedly connected to the other end of the base 11;

[0116] The pickup portion 13 is fixedly disposed at the lower portion of the cantilever frame 12 away from the base 11. The pickup portion 13 is configured to pick up the optical fiber array assembly 2 and drive the optical fiber array assembly 2 to move toward or away from the optical chip.

[0117] The pressure sensor 14 is fixedly arranged at the end of the cantilever frame 12 close to the base 11;

[0118] Among them, a pressure transmission part 121 is formed at the upper end of the cantilever frame 12, and the pressure transmission part 121 is located between the base 11 and the pickup part 13. When the Z-axis motion mechanism 3 drives the optical fiber array assembly 2 to move toward the direction close to the optical chip, when contact pressure is generated between the optical fiber array assembly 2 and the optical chip, the contact pressure is transmitted to the cantilever frame 12 through the pickup part 13, and the cantilever frame 12 is deformed and transmitted to the pressure sensor 14 through the pressure transmission part 121;

[0119] The Z-axis motion mechanism 3 , the pressure sensor 14 and the pickup portion 13 are all electrically connected to the control module.

[0120] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0121] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
