Because the jig can enable the optical coupling of the optical fiber metal bushing and the laser diode to aim at and pass through the first, the second and the third adjusting bolts of the seat body, so as to enable the optical coupling position of the optical fiber metal bushing and the laser diode to be rigidly fixed without generating translocation and to be welded directly with laser.
Description
Technical field
The utility model relates to the be coupled and aligned anchor clamps of usefulness of a kind of photoelectric subassembly, relates in particular to a kind of coaxial laser assembly optically-coupled line-up jig.
Background technology
Coaxial laser assembly as shown in Figure 1, comprise two parts: the laser diode 1 of TO-CAN and optical fiber metal sleeve 2, during coupling, the end face 4 of optical fiber metal sleeve 2 need be fixed with the top 5 of laser diode LD pipe cap, so that laser diode 1 emitted light beams of pipe cap center light window transmission is coupled to the fiber end face 3 back outputs of ferrule 2.At present, coaxial coaxial laser assembly (TOSA) coupling scheme mainly adopt following two kinds of coupling scheme and anchor clamps:
1) adopt the XY diaxon glue to be arranged or do not have glue coupling technique and anchor clamps;
2) adopt three of XYZ glue to be arranged or do not have glue coupling technique and anchor clamps;
The method that glue coupling technique and anchor clamps are arranged when the diaxon that adopts first kind, be that anchor clamps can only be regulated the laser diode 1 of TO-CAN and the surface of contact of optical fiber metal sleeve 2 in the XY plane, and be that the Z axle can not be regulated at optical axis direction, at first need then to adopt instantaneous solidification glue (as ultraviolet glue, 501 etc.) pre-fix the position of adjusting, and then adopt the laser bonding mode finally fixing, this kind mode needed for two steps fixing, it is longer to expend time in, production efficiency is lower, can not satisfy requirements of large-scale production fully, in addition, pre-fix by glue, product hermeticity after the encapsulation is not fine, and product is damp and hot, hot and humid, under the environment such as salt fog, the probability that performance may occur losing efficacy is bigger.And adopt diaxon not have the method for glue coupling technique and anchor clamps, be that the Z axle can not be regulated, by anchor clamps regulate chip of laser X-axis and Y-axis, the luminous power of the LD that optical fiber is coupled to is to maximum, directly adopt the laser bonding mode finally fixing then, this kind mode has solved diaxon has the method production efficiency of glue coupling technique and anchor clamps lower, luminous power diminishes and reliability problems, because not having the Z axle of optical axis direction regulates, only suitable low rate and the coupling of low power LD product, for high-power and optically-coupled two-forty, this method just can not guarantee higher coupling efficiency.
Adopt second kind three of XYZ glue to be arranged or do not have glue coupling technique and anchor clamps, though can solve the coupling efficiency problem of the LD product of high-power and two-forty, adopt its volume and weight of anchor clamps of three no glue coupling usefulness of XYZ all bigger than normal, when anchor clamps are seized optical fiber metal sleeve 2 on both sides by the arms, pilot pin or gib screw and two elastic positioning pins of comprising two rigidity, its XY axle is to fix by flexible adjustment, as shown in Figure 2, the position of X-axis and Y direction can not lock, pre-fix coupling bit in laser welding processes, be easy to displacement, cause coupled optical power little, can reduce production efficiency of products.
Summary of the invention
For overcoming above shortcoming, it is a kind of simple in structure that the utility model provides, and volume is little, and cost is low, three adjustable coaxial laser assembly optically-coupled line-up jigs of the XYZ of no glue.
For reaching above goal of the invention, the utility model provides a kind of coaxial laser assembly optically-coupled line-up jig, comprise: a cover tubular pedestal, the top that is positioned at this pedestal is evenly equipped with four protruded stigmas and flexibly connects first separately and regulate bolt and be used to seize on both sides by the arms the fixed fiber metal sleeve, the center of described pedestal is provided with one and is used to regulate the axial Z axle adjusting of laser diode light bolt, the upper and lower that the Z axle is regulated bolt is respectively equipped with pipe cap and the Z axle setting nut that sleeve pipe is used to put the laser diode of TO-CAN, and described pedestal also has second of two symmetries to regulate bolt to pass described sleeve pipe and be used to hold out against laser diode.
Described pedestal also is provided with the 3rd of two symmetries and regulates the sleeve pipe that bolt is used to hold out against Z axle adjusting bolt.
Because the anchor clamps of said structure adopt and both had been provided with the XY axle that the first adjusting bolt is used to regulate the optical fiber metal sleeve on the same pedestal, be provided with Z axle adjusting bolt again and be used to regulate the axial Z axle of laser diode light, thereby realize that the optically-coupled of coaxial laser assembly is to three effectively adjustings of punctual XYZ, and the optical fiber metal sleeve is aimed at the position with the optically-coupled of laser diode in case can second regulate bolt and the 3rd and regulate bolt and rigidly fixed by what pedestal was provided with when being adjusted to the optimum coupling state, make laser diode and optical fiber metal sleeve can not produce the positioning of XYZ axle again, at this moment, directly will carry out laser bonding between optical fiber metal sleeve and the laser diode, realize both optically-coupled packaging technologies.This clamp structure is simple, and volume is little, is suitable for producing in batches.Do not need pre-fixing of glue during coupling, directly Laser Welding (LBW) is fixed, the reliability of products height.
