Abstract

The invention provides an optical fiber coupling debugging device and method, and mainly solves the problem that the coaxiality and the polarization state cannot be jointly debugged in the prior art.According to the invention, a testing device used for testing the coaxiality of a to-be-adjusted lens group and a laser fiber, a detection device used for detecting the polarization states of the to-be-adjusted lens group and the laser fiber, and an adjustment tool used for adjusting and fixing the to-be-adjusted lens group and the laser fiber according to testing and detection results are used for the detection and joint adjustment of the coaxiality and the polarization states. The optical fiber coupling debugging device and method are simple in adjustment, convenient to operate and high in efficiency.

Description

technical field [0001] The invention relates to the field of optical instrument assembly and adjustment, in particular to a method for adjusting coaxiality and polarization state in the coupling process of laser communication optical fibers. Background technique [0002] In the field of laser communication, optical fibers are mainly used to transmit laser signals. The laser signal is transmitted to the laser emitting mirror group through the laser generator through the optical fiber, and after a series of processing in the optical device, it is output from the laser receiving mirror group. [0003] The connector flange of the laser fiber is connected with the flanges of the laser emitting and receiving mirror groups by screws. This connection method cannot directly ensure that the optical axis of the optical fiber coincides with the optical axis of the corresponding mirror group, nor can it strictly guarantee its polarization direction. [0004] 201922101566.4 provides a to...
