Packaging equipment and method for polarization maintaining fiber butterfly laser

Abstract

The invention provides a packaging device for a polarization-maintaining optical fiber butterfly laser, which includes an optical fiber clamp module, a shell clamp module, a welding module and a visual monitoring module. The optical fiber clamp module clamps the optical fiber and sends it into the shell, adjust The position and angle of the optical fiber are coupled, the shell fixture module clamps and positions the shell, and can power on the shell, the welding module welds the metal sleeve on the coupled optical fiber in the shell, and is used for the visual monitoring module For monitoring the position and angle of the optical fiber; the welding module includes a tail pipe welding assembly arranged on one side of the shell fixture module, on which at least two electrodes are arranged, which can contact and conduct electricity on both sides of the through hole of the shell. The structure design of each module in the present invention is reasonable, and the connection and cooperation are compact, which simplifies the packaging process and improves the production efficiency. At the same time, it solves the problem that it is difficult to weld the metal sleeve at the tail end by using laser welding components, and has the advantages of small deformation of welding parts and easy realization of automatic control. The advantages.

Description

technical field [0001] The invention relates to the technical field of butterfly laser packaging, in particular to a packaging device and method for a polarization-maintaining fiber butterfly laser. Background technique [0002] The light emitted by semiconductor lasers for communication is linearly polarized light. When it is transmitted in a common single-mode fiber, if the fiber is bent or twisted, the polarization state of the optical signal will change. The polarization state of the optical signal is an important optical characteristic. In many applications, there are clear requirements for the polarization state of the optical signal, and a polarization-dependent light source is required. Therefore, it is necessary to directly couple the light emitted by the laser chip into the polarization-maintaining fiber for further processing. use. [0003] Polarization-maintaining fiber is a kind of fiber that transmits linearly polarized light. The use of polarization-maintaini...

Problems solved by technology

In the above solution, the front end of the fiber is fixed on the heat sink by a saddle clamp, and the operation is relatively cumbersome. At the same time, it is difficult to realize the welding between the end of the fiber and the through hole by relying on the laser welding device above. Therefore, there is still room for further optimization of the packaging method of the butterfly laser.
