Description

technical field [0001] The invention belongs to the technical field of optical fiber communication, and more specifically relates to a semiconductor laser V-shaped groove fixing an optical fiber coaxial device. Background technique [0002] In optical fiber communication technology, semiconductor lasers are widely used as signal sources. Since it is necessary to couple the laser emitted by the semiconductor laser into the optical fiber before it can be used in the optical fiber communication system, there are many different types of coupling packaging devices, such as coaxial packaging, dual in-line packaging and butterfly packaging. Because of its low cost, the devices in the coaxial package are widely used in access networks, metropolitan area networks, rack switching, and cable television. Usually semiconductor laser coaxial devices, optical fibers and lasers must be manually coupled and aligned. The specific process is usually to align the optical fiber with the light-...

AI Technical Summary

Problems solved by technology

In this process, since the geometric dimensions of the light-receiving surface and the light-emitting surface of the optical fiber and semiconductor laser are on the order of microns, it takes a lot of labor and time to perform coupling adjustment work to precisely align the two, and it is difficult for the coupling work to be performed. Technicians put forward higher technical level requirements

This makes it difficult to further reduce the cost of semiconductor laser coaxial devices, affecting its further wide application
