All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0019] As an optical component used within an optical module, the optical component inputs optical signals into the module via an optical port. After passing through the optical component, the optical signal is split into multiple outputs. High precision in the spacing between these output signals and stable signal quality are required; therefore, the coupling accuracy and stability of the optical component are crucial. Based on this, see [link to relevant documentation]. Figures 1-4 , Figure 8 This embodiment provides a coupling test system for optical components in an optical module, used to couple the optical port pigtail 18 to the coupling element 19 to obtain an optical component, including: a light source module, a loading module, a feeding module, a position monitoring module, and a beam parameter monitoring module; The light source module is connected to the optical port pigtail 18 via the light source connector and transmits test light to the optical port pigtail 18. The loading module includes a loading adjustment mechanism and a loading platform 8. The loading platform 8 is fixed on the loading adjustment mechanism. During coupling, the coupling element 19 is fixed on the loading platform 8, and the loading adjustment mechanism adjusts the attitude of the coupling element 19. The feeding module is located on one side of the coupling end of the coupling element 19, and includes a feeding adjustment mechanism, a feeding fixture 10, and a suction nozzle mechanism 11. The feeding fixture 10 is fixed on the feeding adjustment mechanism, and the suction nozzle mechanism 11 is fixed on the feeding fixture 10. The feeding fixture 10 fixes the light source connector, and the suction nozzle mechanism 11 adsorbs and fixes the coupling end of the optical port pigtail 18. The feeding adjustment mechanism adjusts the position and orientation of the optical port pigtail 18. The position monitoring module is located on the side between the loading module and the feeding module to monitor the real-time position of the optical fiber 18. A beam parameter monitoring module is set on one side of the optical port of the coupling element 19 to monitor the beam parameters of the output beam of the optical component; the optical port pigtail 18 is coupled with the coupling element 19 to form an optical component, and the test light is emitted from the optical port after passing through the optical component to form the output beam.

[0020] In this embodiment, the location monitoring module is the CCD camera monitoring module 12.

[0021] Furthermore, the light source module includes a multi-wavelength laser source 15 and a multi-channel optical switch 14; the multi-wavelength laser source 15 provides light of multiple wavelengths, and the multi-channel optical switch 14 selects the wavelength of the test light.

[0022] Further, see Figure 5 The load adjustment mechanism is a three-dimensional rotary adjustment table 7; the three-dimensional rotary adjustment table 7 adjusts the rotation angle, pitch angle and roll angle of the coupling element 19.

[0023] Furthermore, the loading platform 8 is provided with adsorption holes, which are connected to an external vacuum pump through the air pipe of the loading platform 8, so that negative pressure is generated on the loading platform 8 to adsorb and fix the coupling element 19.

[0024] Specifically, the air pipe of the cargo platform 8 is fixed to the cargo platform 8 by the cargo platform air pipe fixing mechanism 801.

[0025] Furthermore, a collimator 802 is provided on the side of the cargo platform 8; the collimator 802 emits collimated light, which is received by the beam parameter monitoring module.

[0026] Specifically, the beam parameter monitoring module calculates the height of the output beam spot of the optical component relative to the placement surface of the optical component based on the coordinates of the collimated light. The placement surface is the contact surface between the bottom of the optical component and the platform 8. The side of the platform 8 is provided with a collimator 802 mounting hole, and the collimator 802 is fixed in the collimator 802 mounting hole by a set screw. The collimator 802 is connected to the light source so that the collimator 802 can emit collimated light.

[0027] Further, see Figure 6 The feeding adjustment mechanism is a five-dimensional adjustment platform 9, which adjusts the horizontal position, height, rotation angle, and pitch angle of the optical fiber pigtail 18. The suction mechanism 11 is equipped with an adsorption rod 1101 and a suction mechanism air pipe 1104 that are interconnected.

[0028] Specifically, the loading fixture 10, the five-dimensional adjustment platform 9, and the suction nozzle mechanism 11 are fixed together as a whole by screws. The suction nozzle mechanism 11 is fixed to the loading fixture 10 and is equipped with an adsorption rod 1101 and a suction nozzle mechanism air pipe 1104 that are interconnected (the suction nozzle mechanism air pipe 1104 is fixed to the main body of the suction nozzle mechanism 11 through a suction nozzle mechanism air pipe fixing mechanism 1103). The suction nozzle mechanism air pipe 1104 is connected to an external vacuum pump, which generates negative pressure at the end of the adsorption rod 1101 to adsorb and fix the optical fiber optic pigtail 18. The loading fixture 10 is equipped with a locking mechanism 1001, which is used to fix the light source connector; the suction nozzle mechanism 11 is fixed to the loading fixture 10 through a connecting rod 1002.

The shape of the end of the adsorption rod 1101 can be designed according to the shape of the glass head of the optical fiber optic pigtail 18 to ensure a firm adsorption. The elastic structure 1102 prevents the optical fiber 18 from making hard contact during the reset process after coupling to the site adhesive, which would cause the original coupled data to shift.

[0029] Furthermore, the beam parameter monitoring module includes a two-dimensional guide rail mechanism, a PD power detector 5, and a beam analyzer 6; both the PD power detector 5 and the beam analyzer 6 are fixed on the movable slider of the two-dimensional guide rail mechanism, and the two-dimensional guide rail mechanism adjusts the horizontal position of the PD power detector 5 and the beam analyzer 6; the PD power detector 5 obtains the power value of the output beam, and the beam analyzer 6 obtains the coordinates and diameter of the output beam.

[0030] Specifically, the two-dimensional guide rail mechanism includes a coupled x-axis moving guide rail 3 and a y-axis moving guide rail 4, which can move the PD power detector 5 and the beam analyzer 6 on the horizontal X and Y axes by moving the slider.

[0031] Furthermore, a UV curing module 13 is included, which is positioned above the platform 8; after the optical component is coupled and glue is applied, the UV curing module cures the optical component.

[0032] Furthermore, the shock absorber 2 is included; the feeding module, the loading module, and the beam parameter monitoring module are all set on the shock absorber 2, which is set on the workstation table 1.

[0033] Furthermore, it includes a control module; the load adjustment mechanism adjusts the posture of the coupling element according to the control of the control module, and the feeding adjustment mechanism adjusts the position and posture of the optical port pigtail according to the control of the control module; the control module controls the feeding module to move the optical port pigtail to the coupling position according to the real-time position of the optical port pigtail, and judges whether the coupling is in place according to the beam parameters of the output beam. If it is, the optical port pigtail is fixed to the coupling element; otherwise, the coupling is re-performed.

[0034] See Figure 7 This embodiment also provides a coupling test method for optical components in an optical module, including: S1. Fix the coupling element 19 to the loading module, and adjust the attitude of the coupling element 19 by controlling the loading adjustment mechanism; S2. Connect the optical fiber 18 to the light source connector, fix the light source connector to the loading fixture 10, and use the suction nozzle mechanism 11 to adsorb and fix the coupling end of the optical fiber 18. S3. Monitor the real-time position of the optical fiber pigtail 18 through the position monitoring module; S4. Based on the real-time position of the optical fiber 18, control the feeding adjustment mechanism to adjust the position and attitude of the optical fiber 18 so that the optical fiber 18 moves to the coupling position. S5. Obtain the beam parameters of the output beam of the optical component through the beam parameter monitoring module; S6. Determine whether the coupling is in place based on the beam parameters of the output beam. If it is, fix the optical port pigtail 18 to the coupling element 19; otherwise, re-couple.

[0035] Specifically, in step S1, the coupling element 19 is first placed on the platform 8 (the platform 8 can be designed with a limiting groove according to the structure of the coupling element 19 to ensure that the placement position of the coupling element 19 is consistent each time coupling, thereby improving coupling efficiency). The vacuum pump is turned on, and the vacuum pump generates negative pressure in the adsorption hole through the air pipe of the platform 8, thereby adsorbing and fixing the coupling element 19. When the coupling element 19 is fixed on the platform 8, it is necessary to adjust the three-dimensional rotating adjustment stage 7 to keep the coupling element 19 horizontal.

[0036] Before the optical fiber pigtail 18 is connected to the light source connector, the two-dimensional guide rail mechanism is controlled to move the PD power detector 5 to the output interface of the light source connector. Then, the wavelength of the light output from the output interface of the light source connector is controlled by the multi-channel optical switch 14, and the power values ​​corresponding to different wavelengths are obtained and recorded. .

[0037] In step S2, the optical fiber 18 is first connected to the light source connector, and the light source connector is fixed on the loading fixture 10 by the locking mechanism 1001; the vacuum pump generates negative pressure at the end of the adsorption rod 1101 through the suction nozzle mechanism air pipe 1104, thereby fixing the glass head at the end of the optical fiber 18.

[0038] Step S5 includes: S501. Control the two-dimensional guide rail mechanism to move the beam analyzer 6 to the output end of the collimator 802. At this time, acquire and record the beam spot coordinates of the collimated light output by the collimator 802. ; S502. Control the two-dimensional guide rail mechanism to move the beam analyzer 6 to the output near-field end of the optical component. Control the multi-channel optical switch 14 to change the wavelength of the output beam, and acquire and record the near-field optical coordinate signals of different wavelengths at the output near-field end. , ... and near-field spot diameter , ... Where N is the number of wavelength types; S503: Control the two-dimensional guide rail mechanism to move the PD power detector 5 to the output near-field end of the optical component, and acquire and record the power values ​​corresponding to different wavelengths at this time. ; S504. Control the two-dimensional guide rail mechanism to move the beam analyzer 6 to the far-field output end of the optical component. By controlling the multi-channel optical switch 14 to change the wavelength of the output beam, acquire and record the far-field optical coordinate signals of different wavelengths at the far-field output end. , ... and far-field spot diameter , ... ; Both the output near-field end and the output far-field end mentioned above are located in the light-emitting direction of the optical component. The output near-field end is closer to the optical port of the optical component than the output far-field end. The specific distance settings between the output near-field end, the output far-field end and the optical port are determined according to the specific product. S505. Calculate the x-axis and y-axis emission angles corresponding to each wavelength; the x-axis and y-axis emission angles corresponding to a certain wavelength are expressed as follows: , :

[0039]

[0040] Where L is the relative distance between the output near-field end and the output far-field end; S506. Calculate the height of the spot of the coupled output beam relative to the surface where the optical component is placed. :

[0041] Where d is the distance between the surface of the platform 8 and the center of the mounting hole of the collimator 802.

[0042] S507, Calculate the loss of near-field output light. :

[0043] Step S6 includes: Determine whether the near-field spot diameter, far-field spot diameter, x-axis light output angle, y-axis light output angle, relative spot height, and near-field output light loss corresponding to each wavelength meet the preset requirements. If they meet the requirements, the coupling is considered complete; otherwise, re-coupling is performed.

[0044] In this embodiment, after determining that the coupling is in place, the feeding module is controlled to raise the optical fiber pigtail 18 to a designated position at a certain height. Adhesive is then applied at the coupling point between the optical fiber pigtail 18 and the coupling element 19, and the optical fiber pigtail 18 is reset to the coupling position. During the reset process, the beam analyzer 6 monitors the beam changes. After reset, the UV curing module 13 is controlled to cure the applied adhesive. The UV curing module 13 is set with curing time and curing power. After the curing time is completed, the UV curing module 13 automatically shuts down. After curing, the system will perform another test according to step S5. If the test is successful, the finished optical component is obtained, at which point the optical component can be removed for subsequent production.

[0045] It should be emphasized that in this utility model, the wavelength switching in the light source module, the attitude adjustment of the coupling element by the loading module, the position adjustment of the optical fiber pigtail by the feeding module, and the movement of the position monitoring module can all be manually controlled through corresponding manual adjustment mechanisms (e.g., Figure 5 The implementation of this utility model relies on the combination of the above-mentioned position adjustment modules, rather than the automatic control logic of the control module (those skilled in the art can manually adjust it by viewing the monitoring results).

[0046] Applying this utility model has at least the following beneficial effects: 1. Integrated system coupling test, modular system assembly; the feeding fixture 10 and the suction nozzle mechanism 11 can be customized according to the product structure, which can be applied to more types of product coupling and improve the utilization rate of system equipment; 2. Real-time monitoring of coupling data; The system introduces a collimator 802 to monitor the relative height of the light spot output, ensuring more accurate coupling effect and avoiding insufficient component coupling accuracy caused by monitoring only the light spot diameter, resulting in poor consistency during module assembly; 3. The feeding fixture 10 and the suction nozzle mechanism 11 are customized; the suction nozzle mechanism 11 is designed with an elastic structure 1102 to ensure that the coupling reset will not produce a large coupling offset, and avoid repeated fine-tuning of the coupling due to position offset after coupling reset, which reduces production efficiency. 4. Introduce a PD monitoring device to monitor together with the beam analyzer 6 to avoid the inability to identify poor coupling caused by dirt. If there is dirt on the surface of the component, it will cause excessive loss of the emitted light signal, and the beam spot monitoring cannot reflect this defect. 5. A three-dimensional rotary adjustment stage 7 is added to the loading platform 8, which can calibrate and correct the horizontal state of the coupling element 19 placed on the loading platform 8, so as to avoid the problem of coupling consistency and inaccurate coupling data. 6. The CCD monitoring device synchronously monitors the movement position of the coupling element 19 and, in conjunction with the software control of the coordinate data of the five-dimensional adjustment stage 9, ensures that the suction nozzle mechanism 11, carrying the optical fiber 18, can quickly reach the designated position and then perform fine adjustments during each coupling, thereby improving coupling efficiency.

[0047] It should be noted that, depending on the implementation needs, the various steps / components described in this application can be broken down into more steps / components, or two or more steps / components or parts of the operation of steps / components can be combined into new steps / components to achieve the purpose of this utility model.

[0048] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
