Abstract

Disclosed in the invention is an optical fiber connector comprising a connector body and a segment of bare fiber penetrating the connector body. The connector body includes a metal sleeve, a first fiber fixed component fixed at one end of the metal sleeve, and a second fiber fixed component fixed at the other end of the metal sleeve. The bare fiber includes a first bare fiber passing through the first fiber fixed component and a second bare fiber passing through the second fiber fixed component. Because the metal sleeve and metal solder have good invasion, welding fixation of the optical fiber connector and a laser protection shell can be realized beneficially. Moreover, due to the good thermal conductivity of the metal, the heat can be transmitted to the air through the metal sleeve or be transmitted to the metal solder through the metal sleeve and then to the laser protection shell for dissipation, so that heat dissipation can be carried out beneficially.

Description

technical field [0001] The invention relates to the technical field of optical coupling devices, in particular to an optical fiber connector suitable for receiving and transmitting high-power semiconductor lasers. Background technique [0002] Generally speaking, the optical coupling of spatial light is mainly to focus or image the laser beam emitted by solid-state lasers, semiconductor lasers, etc. on the end face of the fiber core after beam shaping. The light-guiding part of the fiber is composed of the core and the cladding. , the refractive index of the core will be slightly greater than that of the cladding. In this way, when the light divergence angle incident on the end face of the fiber core is smaller than the numerical aperture NA of the fiber, it will be at the interface between the core and the cladding after entering the core. Total reflection occurs at , and when the divergence angle of light incident on the end face of the fiber core is greater than the numer...
