Abstract

A photodetector tail fiber coupling and bonding device belongs to the technical field of optoelectronic device tail fiber coupling and bonding. The invention adopts fine processing technology to realize the alignment of the tail fiber fixing block and the tail hole of the package shell, and uses the optical fiber adhesive to fix the pigtail in the tail pipe of the package shell, the pigtail does not need metallization treatment, and uses a heating plate to heat the package shell fixing block , Curing the pigtail adhesive to complete the pigtail bonding, using PTFE material (heat insulation material) rivets to connect the pigtail fixing block and the package shell fixing block to avoid heat conduction between the two fixing blocks and protect the pigtail.

Description

technical field [0001] The invention belongs to the technical field of fiber pigtail coupling and bonding of optoelectronic devices, and in particular relates to a photodetector pigtail fiber coupling and bonding device. Background technique [0002] The photodetector converts the optical signal into an electrical signal, which is one of the indispensable components in optical fiber sensing and optical communication. The external optical signal enters the interior of the photodetector through the photodetector pigtail, and the coupling accuracy of the photodetector pigtail, Stability affects key parameters of a photodetector: current responsivity and its temperature stability. [0003] At present, the coupling of photodetector pigtails is mostly aligned by adjusting frame, and fixed by glass solder or soldering. , the existing tooling and fixing methods cannot be used. Contents of the invention [0004] The technical problem solved by the present invention is: to overcom...
