Description

Technical Field

[0001] The present application relates to the technical field of superluminescent diode manufacturing, and in particular to a superluminescent diode pre-coupled optical fiber fixing fixture. Background Art

[0002] Superluminescent diodes (SLDs) have developed rapidly in recent years. They are semiconductor optoelectronic devices between lasers (LDs) and light-emitting diodes (LEDs). They have the characteristics of high output power and wide spectral width, and are suitable for applications such as optical coherence tomography (OCT) imaging systems and fiber optic gyroscopes (FOGs).

[0003] In the production of superluminescent diodes (SLDs), specifically, the pre-coupled optical fiber of the superluminescent diode (SLD) needs to use a coupling table, and the front end of the lens optical fiber needs to be accurately aligned and fixed with glue, and then cured by ultraviolet light, and the appropriate spatial position is adjusted for fine tuning. The optical power value is detected, and the smaller the optical loss efficiency, the better, and the smaller the uniformity of the light, the better, to ensure the transmission quality and stability of the optical signal, so the correct position of the pre-coupled optical fiber needs to be maintained before curing.

[0004] At present, the position of the pre-coupled optical fiber is generally maintained manually. The position of the optical fiber is difficult to control. If the position is offset, it is difficult to adjust after curing. Once cured, the glue is not easy to remove, so it takes more time and labor costs. Because the viscosity of the glue before curing is not strong enough, the optical fiber is prone to loosening or vibration, which directly affects the efficiency of the superluminescent diode pre-coupling. Therefore, it is urgent to invent a clamp that can fix the position of the pre-coupled optical fiber. Summary of the invention

[0005] The present application provides a superluminescent diode pre-coupled optical fiber fixing fixture, which solves the problem that when the superluminescent diode is pre-coupled with an optical fiber, the position of the pre-coupled optical fiber is easily shifted by artificially maintaining the position of the pre-coupled optical fiber.

[0006] The present application provides a superluminescent diode pre-coupled optical fiber fixing fixture, comprising a base plate, the top surface of the base plate is provided with a limiting groove for placing the pre-coupled optical fiber, a pressing block is rotatably installed on the front end side of the base plate corresponding to the limiting groove, and the pressing block cooperates with the limiting groove to clamp and fix the pre-coupled optical fiber.

[0007] In the technical solution provided in the present application, the pre-coupled optical fiber can be firmly fixed in the limiting groove by rotating the pressing block and pressing the pressing block on the limiting groove of the bottom plate, which can effectively prevent the pre-coupled optical fiber from shifting before the glue is cured, thereby improving the efficiency of the superluminescent diode pre-coupling.

[0008] In some embodiments, the limiting groove includes a fiber limiting groove, an avoidance groove and a clamping groove connected in sequence, and the fiber limiting groove, the avoidance groove and the clamping groove respectively correspond to the fiber sleeve, the nickel tube and the fiber metallized part for placing the pre-coupled optical fiber, and the depth of the avoidance groove is deeper than that of the fiber limiting groove and the clamping groove; since the nickel tube is used to connect the fiber metallized part and the fiber sleeve, there is glue at the connection, the shape is irregular and the diameter is thick, therefore, by setting the avoidance groove, the nickel tube can be kept in a suspended state, avoiding damage to the nickel tube when the pressing block is buckled with the bottom plate.

[0009] In some embodiments, the radial cross-section of the clamping groove is "V"-shaped. By designing the V-shaped clamping groove and cooperating with the pressure block to clamp the metallized part of the front end of the optical fiber, the force points on the two inner walls of the V-shaped clamping groove and the force points on the bottom of the pressure block form a triangular structure, which is more stable.

[0010] In certain embodiments, two ear plates are installed in parallel on the bottom plate, and the hinged end of the pressing block is rotatably installed between the two ear plates via a pin shaft.

[0011] In some embodiments, a first magnetic block is embedded in the bottom surface of the pressing block, and a second magnetic block matching the first magnetic block is embedded in the top surface of the base plate, and the pressing block and the base plate clamp and fix the pre-coupled optical fiber through the attraction of the first magnetic block and the second magnetic block; the pressing block and the base plate are snapped together by magnetic attraction, and opening and closing the clamp is very convenient and easy to operate, and the magnetic block can provide pre-tightening pressure to make the pressing block and the base plate clamp the pre-coupled optical fiber more firmly.

[0012] In some embodiments, a buffer pad is embedded in the bottom surface of the pressing block, and the position of the buffer pad corresponds to the position of the limiting groove. By providing the buffer pad on the bottom surface of the pressing block, when the pressing block is magnetically fastened to the bottom plate, a rigid collision between the pressing block and the metallized part of the optical fiber can be avoided, thereby avoiding damage to the optical fiber.

[0013] In some embodiments, the opening and closing ends of the pressing block are provided with handles to facilitate opening or closing the pressing block.

[0014] In some embodiments, the base plate is provided with a plurality of mounting holes for fixing the base plate on the coupling platform.

[0027] In the technical solution provided in the present application, by rotating the pressing block 2 and pressing the pressing block 2 on the limiting groove of the base plate 1, the pre-coupled optical fiber can be firmly fixed in the limiting groove, which can effectively prevent the pre-coupled optical fiber from shifting before the glue is cured, thereby improving the efficiency of the superluminescent diode pre-coupling.

[0028] Please continue reading Figure 1 In some embodiments, the limiting groove includes a fiber limiting groove 3, an avoidance groove 4 and a clamping groove 5 connected in sequence, and the fiber limiting groove 3, the avoidance groove 4 and the clamping groove 5 respectively correspond to the fiber sleeve 6, the nickel tube 7 and the fiber metallized part 8 for placing the pre-coupled optical fiber, and the depth of the avoidance groove 4 is deeper than that of the fiber limiting groove 3 and the clamping groove 5; since the nickel tube 7 is used to connect the fiber metallized part 8 and the fiber sleeve 6, there is glue at the connection, the shape is irregular and the diameter is thick, therefore, by setting the avoidance groove 4, the nickel tube 7 can be kept in a suspended state to avoid damage to the nickel tube 7 when the pressing block 2 is buckled with the base plate 1.

[0029] In some embodiments, the radial cross-section of the clamping groove 5 is "V"-shaped. By designing the V-shaped clamping groove 5 and cooperating with the pressing block 2 to clamp the metallized part of the front end of the optical fiber, the force points on the two inner walls of the V-shaped clamping groove 5 and the force points on the bottom surface of the pressing block 2 form a triangular structure, which is more stable.

[0030] Please continue reading Figure 1 In some embodiments, two ear plates 9 are installed in parallel on the base plate 1, and the hinged end of the pressing block 2 is rotatably installed between the two ear plates 9 through a pin shaft.

[0038] First, open the pressing block 2, put the optical fiber to be coupled into the limiting groove, make the metallized part of the front end of the optical fiber located in the V-shaped clamping groove 5, make the nickel tube 7 located in the avoidance groove 4, make the optical fiber sleeve 6 located in the optical fiber limiting groove 3, and adjust the position of the optical fiber; then buckle the pressing block 2, and after the pressing block 2 is buckled, it and the base plate 1 are attracted to each other through the magnetic suction block to provide a pre-tightening force to clamp the optical fiber, which can effectively prevent the pre-coupled optical fiber from vibrating or shifting, and ensure the stability of the fixation of the pre-coupled optical fiber.
