Description

Technical Field

[0001] This invention relates to the field of semiconductor laser technology, and more particularly to an optical fiber coupling device and method with a ceramic ferrule. Background Technology

[0002] Semiconductor lasers are increasingly widely used in communications, military, and medical fields. As a semiconductor component, the market demand for semiconductor lasers is constantly increasing. Generally speaking, the mainstream process for incorporating fiber optic assemblies with ceramic ferrules into semiconductor laser products is currently, which mainly falls into three categories: First, passive alignment based on the mechanical precision of the ferrule's outer diameter (such as using precision ceramic sleeves), whose loss is limited by the cumulative effect of multiple tolerance levels, resulting in poor consistency in direct alignment assembly; second, active alignment based on optical power feedback, but this usually requires large equipment, involves cumbersome processes, is inefficient, and struggles to solve the misalignment problem during coupling and curing; and third, the consistency of the laser spot after coupling in fibers with ceramic ferrules.

[0003] However, in the practical scenario of mass production of semiconductor lasers with ceramic ferrules, existing technologies still have many obvious defects. The alignment dimension is relatively free, the ferrule is inserted into the device slot at an angle, the alignment and curing processes are disconnected, the adhesive shrinks during curing, and there is a lack of management of the overall stress of the fiber optic assembly (such as fiber bending), which affects long-term reliability. Therefore, how to design a fiber optic coupling device and related coupling methods that can achieve precise alignment and curing control of ceramic ferrules, ensure the consistency of the output beam, improve coupling accuracy and production efficiency, optimize stress management and enhance device reliability, and adapt to the needs of mass production and R&D testing has become an urgent problem for researchers in this field. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings mentioned above by providing an optical fiber coupling device and method with ceramic ferrules, which enables precise coupling of optical fibers, consistent light spots, and high reliability.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an optical fiber coupling device with a ceramic ferrule, comprising: The installation platform is equipped with a displacement adjustment module, a reflector assembly, a micrometer head clamping assembly, a camera assembly, an auxiliary fixing assembly, and a curing assembly in sequence. The mirror assembly is disposed at the moving end of the displacement adjustment module. The displacement adjustment module is used to drive the mirror assembly to move closer to or further away from the micrometer head clamping assembly in the horizontal direction, and it can also drive the mirror assembly to move up and down in the vertical direction. The micro-head clamping assembly is used to clamp and position the ceramic ferrule; The camera assembly, in conjunction with the mirror assembly, can perform imaging, uniformity analysis, and optical path parameter reading of the reflected light spot; The curing component is used for curing the adhesive after the ceramic ferrule is coupled and positioned. The auxiliary fixing component is used to fix the corresponding device and can also suspend optical fibers with ceramic ferrules.

[0006] Furthermore, the reflector assembly includes a mounting base disposed at the moving end of the displacement adjustment module. The mounting base is provided with a positioning block, and the positioning block has a light-emitting hole. The positioning block is also provided with a reflector lens and a collimating lens. The collimating lens is located between the light-emitting hole and the reflector lens, and they are both coaxially arranged.

[0007] Furthermore, the micrometer head clamping assembly includes a connecting frame disposed on the mounting platform. A first clamping frame is hinged to one end of the connecting frame. A driving component configured with a corresponding micrometer head is disposed on the connecting frame. A second clamping frame is disposed at the moving end of the driving component. The driving component is used to drive the second clamping frame to move towards or away from the first clamping frame. A positioning groove adapted to the ceramic ferrule and used to clamp and position the ceramic ferrule is provided between the first clamping frame and the second clamping frame. A tension spring is also provided between the connecting frame and the first clamping frame. The tension spring is used to pull the first clamping frame and keep it in a clamping state for the ceramic ferrule in the vertical direction.

[0008] Furthermore, the camera assembly includes a bracket mounted on the mounting platform, on which a camera body is mounted, the camera body being a CCD camera.

[0009] Furthermore, the auxiliary fixing component includes a limiting component and an optical fiber bracket. The limiting component includes an assembly plate disposed on the positioning block. A horizontally inverted semiconductor laser device is disposed in the assembly plate. A storage base is disposed on the mounting platform. The assembly plate is slidably disposed in the storage base. A spring-loaded plunger is slidably disposed on the storage base. One end of the plunger extends into the storage base, and a limiting plate is disposed at that end. The limiting plate abuts against the assembly plate, and it can cooperate with the plunger to abut the assembly plate against the inner wall of the storage base. The irradiation end of the semiconductor laser device is coaxially arranged with the light output aperture; The fiber optic bracket is vertically mounted on the storage base and is used to suspend optical fibers with ceramic ferrules.

[0010] Furthermore, the curing assembly includes an assembly frame component and a curing lamp. The assembly frame component includes a first assembly frame disposed on the mounting platform, a second assembly frame rotatably disposed on the first assembly frame, and a rotating handle for limiting the second assembly frame on the first assembly frame. The curing lamp is located at the end of the second assembly frame away from the first assembly frame, and the irradiation end of the curing lamp faces the ceramic insert clamping part of the micron head clamping assembly.

[0011] An optical fiber coupling method with a ceramic ferrule includes the following steps: S1: Place the semiconductor laser device horizontally upside down into the assembly board, and push the assembly board into the storage base. The assembly board is pressed and fixed by the spring-loaded plunger, the limiting plate and the storage base to prevent the device from tilting and shifting. S2: Suspend the optical fiber with ceramic ferrule on the optical fiber bracket, place the ceramic ferrule from the side of the device into the light output hole, and use the clamping end of the micro-head clamping assembly in conjunction with the tension spring to achieve stable clamping of the ceramic ferrule in the vertical direction. S3: The displacement adjustment module drives the reflector assembly to move horizontally or vertically, so that the collimating lens is co-centered with the light outlet and at the working focal point, so as to ensure that the laser light path is coaxial with the center of the collimating lens. S4: Using a reverse light transmission method, laser light is transmitted from the outside to the semiconductor laser device. After being collimated by the collimating lens and reflected by the reflecting lens, the laser light directly enters the detection field of view of the camera body. The camera assembly images the reflected light spot, and the external computer system analyzes the shape and uniformity of the light spot and reads the relevant parameters of the optical path in real time. S5: The micro-adjustment micro-head clamping assembly's micro-head, in conjunction with the drive component, pushes the second clamping frame to move, causing the ceramic ferrule to perform two-dimensional precision position adjustment. During the adjustment process, the camera body monitors the spot state in real time until a stable and uniform optimal spot image is read, thus determining the optimal coupling position of the ceramic ferrule. S6: The optimal coupling position of the ceramic ferrule is cured with adhesive using an auxiliary fixing component package to complete the fiber coupling operation with the ceramic ferrule.

[0012] Furthermore, in step S4, the reverse-transmitting laser beam is reflected by the reflective lens and directly enters the detection field of view of the camera body, and the optical path related parameters are read in real time during the spot analysis process.

[0013] Furthermore, the displacement adjustment of the ceramic ferrule in step S5 is monitored in real time by the camera body.

[0014] The beneficial effects of this invention are reflected in: In this invention, an auxiliary fixing component secures the semiconductor laser device and suspends the fiber with a ceramic ferrule. A displacement adjustment module moves the reflector assembly horizontally and vertically to adjust the optical path position. A micro-head clamping component clamps and positions the ceramic ferrule. Subsequently, an external light source, in conjunction with the semiconductor laser device, transmits light in reverse. The light is then reflected by the reflector assembly. A camera component images the reflected light spot, analyzes its uniformity, and reads the optical path parameters. Based on this, the ceramic ferrule is adjusted to the optimal coupling position. A curing component then cures the adhesive, achieving precise coupling of the fiber with the ceramic ferrule. The displacement adjustment module, in conjunction with the reflector assembly, enables precise adjustment of the optical path. Combined with real-time spot monitoring by the camera component and the ceramic ferrule positioning by the micro-head clamping component, coupling alignment accuracy is ensured. The auxiliary fixing component provides stable fixation of the device and the fiber, while the curing component completes precise curing after coupling. This effectively improves the light output consistency of the fiber coupling, simplifies the operation process, and enhances the production efficiency and product reliability of semiconductor laser fiber coupling.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-8 The present invention discloses an optical fiber coupling device with a ceramic ferrule, including an installation platform 1, on which a displacement adjustment module 2, a reflector assembly 3, a micrometer head clamping assembly 4, a camera assembly 5, an auxiliary fixing assembly, and a curing assembly are sequentially arranged.

[0019] In one embodiment, the reflector assembly 3 is disposed at the moving end of the displacement adjustment module 2. The displacement adjustment module 2 is used to drive the reflector assembly 3 to move closer to or further away from the micrometer head clamping assembly 4 in the horizontal direction. It can also drive the reflector assembly 3 to move up and down in the vertical direction. The micrometer head clamping assembly 4 is used to clamp and position the ceramic ferrule. The camera assembly 5 can cooperate with the reflector assembly 3 to image the reflected light spot, perform uniformity analysis, and read optical path parameters. The curing assembly is used for curing the adhesive after the ceramic ferrule is coupled and positioned. The auxiliary fixing assembly is used to fix the corresponding device and can also suspend the optical fiber with the ceramic ferrule.

[0020] In practical implementation, during operation, the auxiliary fixing component secures the semiconductor laser device and suspends the fiber with ceramic ferrule. The displacement adjustment module 2 moves the reflector assembly 3 horizontally and vertically to adjust the optical path position. The micro-head clamping assembly 4 clamps and positions the ceramic ferrule. Subsequently, an external light source, in conjunction with the semiconductor laser device, transmits light in reverse. After reflection by the reflector assembly 3, the camera assembly 5 images the reflected light spot, analyzes its uniformity, and reads the optical path parameters. Based on this, the ceramic ferrule is adjusted to the optimal coupling position. Then, the curing component completes the adhesive curing, achieving precise coupling of the fiber with ceramic ferrule. The displacement adjustment module 2, in conjunction with the reflector assembly 3, enables precise adjustment of the optical path. Combined with real-time spot monitoring by the camera assembly 5 and the positioning of the ceramic ferrule by the micro-head clamping assembly 4, the coupling alignment accuracy is ensured. The auxiliary fixing component ensures stable fixation of the device and the fiber, and the curing component completes precise curing after coupling. This effectively improves the output consistency of the fiber coupling, simplifies the operation process, and enhances the production efficiency and product reliability of semiconductor laser fiber coupling.

[0021] It should be noted that the displacement adjustment module 2 includes two independent drive slides. One drive slide can drive the other drive slide to move in its horizontal direction, while the reflector assembly 3 is mounted on the other drive slide, which can drive the reflector assembly 3 to move in the vertical direction, thereby ensuring that the reflector assembly 3 can be flexibly adjusted. The displacement adjustment module 2 mentioned above is common knowledge in the field, so its specific structural composition and working principle will not be described in detail in this article.

[0022] In one embodiment, the reflector assembly 3 includes a mounting base 301 mounted on the corresponding other drive slide of the displacement adjustment module 2. A positioning block 302 is mounted on the mounting base 301. A light-emitting hole 303 is opened on the positioning block 302. A reflector 304 and a collimating lens 305 are also mounted on the positioning block 302. The collimating lens 305 is located between the light-emitting hole 303 and the reflector 304, and they are all coaxially arranged.

[0023] In practice, the externally introduced laser enters through the light exit hole 303, and is first collimated by the coaxially arranged collimating lens 305. Then, it is reflected by the reflecting lens 304 to form a detection spot. The camera assembly 5 is used to image and analyze the spot, thereby ensuring the positioning accuracy of the ceramic ferrule coupling. The coaxial arrangement of the light exit hole 303, collimating lens 305, and reflecting lens 304 ensures the coaxiality of the optical path of laser transmission and reflection, effectively improving the accuracy of spot detection. At the same time, the integrated structural design, combined with the movement adjustment of the displacement adjustment module 2, can quickly adapt to the optical path adjustment requirements, further improving the alignment accuracy of the ceramic ferrule fiber coupling and ensuring the consistency of the emitted light spot after coupling.

[0024] In one embodiment, the micrometer head clamping assembly 4 includes a connecting frame 401 mounted on the mounting platform 1. A first clamping frame 402 is hinged to one end of the connecting frame 401. A driving component 403 configured with a corresponding micrometer head is mounted on the connecting frame 401. A second clamping frame 404 is mounted at the moving end of the driving component 403. The driving component 403 is used to drive the second clamping frame 404 to move closer to or further away from the first clamping frame 402. A positioning groove 405 adapted to the ceramic ferrule and used to clamp and position the ceramic ferrule is provided between the first clamping frame 402 and the second clamping frame 404. A tension spring 406 is also installed laterally between the connecting frame 401 and the first clamping frame 402. The tension spring 406 is used to pull the first clamping frame 402 and keep it in a clamping state for the ceramic ferrule in the vertical direction.

[0025] In specific implementation, the driving component 403 can be an electric cylinder structure. When the micro-head clamping assembly 4 is working, it first drives the second clamping frame 404 to move closer to or further away from the first clamping frame 402 through the driving component 403 equipped with the micro-head, until the positioning groove 405 between their sides is used to adapt and precisely clamp the ceramic ferrule. During the clamping process, the tension spring 406 between the connecting frame 401 and the first clamping frame 402 continuously pulls the first clamping frame 402, thereby maintaining a stable clamping state of the ceramic ferrule in the vertical direction. The micro-head setting can realize two-dimensional precision position adjustment of the ceramic ferrule. This structure ensures the accuracy of ceramic ferrule clamping and positioning through the precise driving of the micro-head and the driving component 403 and the adaptation design of the positioning groove 405. The tension spring 406 effectively avoids ferrule offset during adjustment and curing, which not only improves the alignment accuracy of fiber coupling, but also ensures the convenient operation of the clamping structure, thus further improving the overall efficiency of coupling operation.

[0026] In one embodiment, the camera assembly 5 includes a bracket 501 mounted on a mounting platform 1, and a camera body 502, which is a CCD camera, is mounted on the bracket 501.

[0027] In practice, bracket 501 fixes camera body 502 on mounting platform 1 to receive laser spot reflected by mirror assembly 3 during fiber coupling. Camera body 502 completes spot imaging, realizes spot uniformity analysis and optical path parameter reading, and provides accurate visual reference for ceramic ferrule position adjustment. This component uses CCD camera as the core to realize real-time spot monitoring and parameter acquisition, thereby ensuring the consistency of light output of fiber coupling and improving overall coupling accuracy and operation efficiency.

[0028] In one embodiment, the auxiliary fixing component includes a limiting component 6 and an optical fiber bracket 7. The limiting component 6 includes an assembly plate 601 mounted on a positioning block 302. A horizontally inverted semiconductor laser device is disposed in the assembly plate 601. A storage base 602 is mounted on the mounting platform 1. The assembly plate 601 is slidably disposed in the storage base 602. A spring-loaded plunger 603 is slidably mounted on the storage base 602. One end of the plunger 603 extends into the storage base 602, and a limiting plate 604 is mounted on that end. The limiting plate 604 abuts against the assembly plate 601, and can cooperate with the plunger 603 to abut the assembly plate 601 against the inner wall of the storage base 602. In addition, the irradiation end of the semiconductor laser device is coaxially arranged with the light output hole 303, and the optical fiber bracket 7 is vertically mounted on the storage base 602 for suspending optical fibers with ceramic ferrules.

[0029] In practice, the semiconductor laser device is placed horizontally upside down on the assembly plate 601, and then the assembly plate 601 is slid into the storage seat 602 mounted on the mounting platform 1. A spring-loaded plunger 603 on the storage seat 602 pushes the limiting plate 604 to move, thereby abutting against the assembly plate 601 and pressing it firmly against the inner wall of the storage seat 602. This elastic abutment structure ensures the stable fixation of the semiconductor laser device, effectively preventing tilting and positional displacement. Simultaneously, it precisely ensures that the device's irradiation end and the light-emitting aperture 303 are coaxially aligned, ensuring good alignment accuracy of the subsequent optical path. The fiber optic bracket 7, vertically mounted on the storage base 602, can neatly suspend the fiber optic cable with ceramic ferrule. Specifically, the fiber optic bracket 7 has a corresponding number of grooves, which can accommodate fiber optic cables of a corresponding length coiled at a designated position on the fiber optic bracket 7 (corresponding to the groove, and the number of coils corresponds to the number of grooves). This ensures its initial fixation stability. Subsequently, the other end of the fiber optic cable is straightened and allowed to hang downwards, thereby avoiding problems such as bending of the fiber optic cable due to random placement, reducing the impact of fiber optic stress, and facilitating subsequent curing processes.

[0030] In one embodiment, the curing assembly includes an assembly frame component 8 and a curing lamp 9. The assembly frame component 8 includes a first assembly frame 801 mounted on the mounting platform 1, a second assembly frame 802 rotatably mounted on the first assembly frame 801, and a rotating handle 803 for limiting the second assembly frame 802 rotatably mounted on the first assembly frame 801. The curing lamp 9 is mounted on the end of the second assembly frame 802 away from the first assembly frame 801, and the irradiation end of the curing lamp 9 faces the ceramic ferrule clamping position of the micron head clamping assembly 4.

[0031] In practice, the first assembly frame 801 provides support, and the angle and position of the curing lamp 9 can be flexibly adjusted by rotating the second assembly frame 802. After the position is adjusted, it can be limited by rotating the handle 803. When in use, after the curing lamp 9 is turned on, its irradiation end can be accurately aligned with the ceramic ferrule clamping position of the micro-head clamping component 4, so as to adapt to the precise curing requirements of different situations or environments. Finally, the curing light is precisely applied to the coupling position of the ceramic ferrule to ensure the curing effect of the glue and complete the ferrule coupling curing operation.

[0032] In one embodiment, an optical fiber coupling method with a ceramic ferrule is also included, comprising the following steps: S1: The semiconductor laser device is placed horizontally upside down into the assembly plate 601, and the assembly plate 601 is pushed into the storage seat 602. The spring-loaded plunger 603 cooperates with the limiting plate 604 and the storage seat 602 to press and fix the assembly plate 601 to prevent the device from tilting and shifting. S2: Suspend the optical fiber with ceramic ferrule on the optical fiber bracket 7, place the ceramic ferrule from the side of the device into the light output hole 303, and use the clamping end of the micro-head clamping assembly 4 in conjunction with the tension spring 406 to achieve stable clamping of the ceramic ferrule in the vertical direction. S3: The displacement adjustment module 2 drives the reflector assembly 3 to move horizontally or vertically, so that the collimating lens 305 is co-centered with the light outlet 303 and is in the working focal position, so as to ensure that the laser light path is coaxial with the center of the collimating lens 305. S4: Using a reverse light transmission method, laser light is transmitted from the outside to the semiconductor laser device. After being collimated by the collimating lens 305 and reflected by the reflecting lens 304, the laser light directly enters the detection field of view of the camera body 502. The camera assembly 5 images the reflected light spot, and the shape and uniformity of the light spot are analyzed by the external computer system, and the relevant parameters of the optical path are read in real time. S5: The micro-adjustment micro-head clamping assembly 4, together with the drive component 403, pushes the second clamping frame 404 to move, thereby driving the ceramic ferrule to perform two-dimensional precision position adjustment. During the adjustment process, the camera body 502 monitors the spot state in real time until a stable and uniform optimal spot image is read, and the optimal coupling position of the ceramic ferrule is determined. S6: The optimal coupling position of the ceramic ferrule is cured with adhesive using an auxiliary fixing component package to complete the fiber coupling operation with the ceramic ferrule.

[0033] Preferably, in step S4, the reverse-transmitting laser beam, after being reflected by the reflective lens 304, directly enters the detection field of the camera body 502. Furthermore, during the spot analysis process, relevant optical path parameters are read in real time. This method reduces additional losses and offset interference in optical path transmission, ensuring the accuracy and authenticity of spot imaging and optical path parameter detection. Simultaneously, the use of corresponding monitoring devices to read relevant optical path parameters in real time provides immediate and reliable data for adjusting the position of the ceramic ferrule, making coupling position adjustment more efficient and precise. It can quickly locate the optimal coupling position of the ceramic ferrule, thereby ensuring the consistency of the output light spot in the fiber coupling and improving overall coupling accuracy and operational efficiency.

[0034] The monitoring devices mentioned above are common knowledge in this field, so their specific structural composition and working principle will not be elaborated on in this article.

[0035] Preferably, the displacement adjustment of the ceramic ferrule in step S5 is monitored in real time by the camera body 502.

[0036] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

S3: The displacement adjustment module (2) drives the reflector assembly (3) to move laterally or up and down, so that the collimating lens (305) and the light outlet (303) are co-centered and at the working focal point, so as to ensure that the laser light path is coaxial with the center of the collimating lens (305); S4: Using a reverse light transmission method, laser light is transmitted from the outside to the semiconductor laser device. After being collimated by the collimating lens (305) and reflected by the reflecting lens (304), the laser light directly enters the detection field of the camera body (502). The camera assembly (5) images the reflected light spot, and the external computer system analyzes the shape and uniformity of the light spot and reads the relevant parameters of the optical path in real time. S5: The micro-adjustment micro-head clamping assembly (4) is used to move the second clamping frame (404) in conjunction with the drive component (403), thereby driving the ceramic ferrule to perform two-dimensional precision position adjustment. During the adjustment process, the camera body (502) monitors the spot status in real time until a stable and uniform optimal spot image is read, and the optimal coupling position of the ceramic ferrule is determined. S6: The optimal coupling position of the ceramic ferrule is cured with adhesive using an auxiliary fixing component package to complete the fiber coupling operation with the ceramic ferrule.
