Optical fiber coupling module

Abstract

The invention discloses an optical fiber coupling module, which comprises a shell and optical assembles, wherein the shell is provided with optical channels. The optical fiber coupling module is characterized in that a lens is located at a light propagation path of the optical assembly; a hollow socket assembly is connected at the optical channel in a ring manner; a limiting member is located inside the socket assembly, and the limiting member is provided with a through hole which is mutually communicated with the optical channel; and the limiting member comprises a contact surface which prevents an optical fiber jumper from moving, when an external optical fiber jumper is inserted into a cavity of the socket assembly, the end face of the optical fiber jumper is contacted with the contact surface of the limiting member, and light is coupled to the optical fiber jumper through the lens, the optical channel and the through hole. According to the technical scheme disclosed by the invention, the socket assembly is internally provided with the limiting member with the contact surface which has excellent coupling efficiency, the external optical fiber jumper is enabled to acquire excellent light coupling efficiency by being inserted into the bottom part of the socket assembly and arriving at the contact surface, the convenience in light coupling efficiency adjustment is improved, and replacement and maintenance of the optical fiber jumper are facilitated.

Description

technical field [0001] The invention belongs to the technical field of manufacturing optical communication components, and in particular relates to an optical fiber coupling module. Background technique [0002] In existing laser displays or other occasions that require high-power laser output, semiconductor lasers are usually used as light sources. The output power of a single semiconductor laser or semiconductor laser packaging module is low, which often cannot meet the requirements of laser display for high-power laser light sources. In practical applications, it is often necessary to shape and combine the output lights of multiple independent semiconductor lasers together for output. [0003] At present, there are two ways to combine the output light of multiple semiconductor lasers, the micro-optical system coupling method and the fiber array coupling method. In practical application, the optical fiber coupling method mainly fixes the output optical fiber and the optic...
