Contact surface limiting piece of optical fiber coupling module

Abstract

The invention discloses a contact surface limiting piece of an optical fiber coupling module. The contact surface limiting piece comprises an outer frame, a mounting block, a semiconductor laser and two locking devices, wherein the bottom of the semiconductor laser is in contact with the top of the inner wall of the outer frame; the front surface and the back surface of the mounting block are bothfixedly connected with the inner wall of the outer frame; the back surfaces of the locking devices are fixedly connected with the front surface of the outer frame; a mounting groove is formed in themounting block; a bidirectional threaded rod is rotationally connected between the front surface and the back surface of the inner wall of the mounting groove through a bearing; and a through hole isformed in one side of the mounting groove in the mounting block. The contact surface limiting piece relates to the technical field of semiconductor lasers. According to the contact surface limiting piece of the optical fiber coupling module, the limiting and fixing can be achieved to a certain extent when a plurality of semiconductor laser modules are used; the disassembly and maintenance are convenient; the convenience is brought to a user; and meanwhile, a certain protection effect can be achieved for the user.

Description

Technical field [0001] The invention relates to the technical field of semiconductor lasers, in particular to a contact surface limiter of an optical fiber coupling module. Background technique [0002] Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working materials. Due to the differences in the material structure, the specific processes of different types of lasers are relatively special. Common working materials include gallium arsenide, cadmium sulfide, indium phosphide and sulfide Zinc, etc., there are three types of excitation methods: electric injection, electron beam excitation and optical pumping. Semiconductor laser devices can be divided into homojunction, single heterojunction and double heterojunction. Homojunction laser and single heterojunction Mass junction lasers are mostly pulsed devices at room temperature, while double heterojunction lasers can achieve continuous operation at room temperature.
