Description

technical field [0001] The invention relates to the field of optical communication, in particular to a jig for automatic coupling laser welding of a laser emitter. Background technique [0002] With the wide application of broadband services, the demand for optical transceiver modules is also increasing. As a necessary component of optical transceiver modules, miniaturized semiconductor laser transmitters are in increasing demand. Long-term stability requirements are also more stringent. The coupled laser welding of the semiconductor laser transmitter socket directly affects the working performance and long-term reliability of the laser. During the laser welding socket process, the coupling accuracy and the deformation of the solder joint after laser welding have a significant impact on product performance. When welding the socket, in order to make the socket It can be adjusted in the Z-axis direction to obtain better coupling efficiency, and a Z-shaped sleeve is set betwee...

AI Technical Summary

Problems solved by technology

In the prior art, it is impossible to be absolutely level when placing the product to be welded, and there will be dimensional tolerances on the welding surface of the product shell and the welding surface of the Z-shaped sleeve, which will cause the welding surface of the product to be non-level

In addition, the clamping socket will also make the welding surface of the Z-type sleeve not horizontal, which will cause low coupling optical power during the coupling process, and at the same time, the gap between the welding surface of the Z-type sleeve and the welding surface of the product will be in the After the laser welding is completed, the optical axis of the product will be displaced due to the uneven stress of the solder joints, which will greatly reduce the output optical power of the product, thereby reducing the performance of the product and even becoming a defective product
