Problems solved by technology

However, at present, the production of optical devices relies heavily on the skills and technical level of personnel. During the coupling process of the three-body coaxial optical device, the polarization angle of the isolator is still found by manually rotating the isolator. The production efficiency is low and the performance and consistency of the device cannot be obtained. Assure

The automatic coupling device has the advantages of reasonable structural design, high degree of automation, high production efficiency, low production cost, stable product quality, wide application range and the like.

Description

technical field [0001] The invention relates to the technical field of automatic coupling and packaging of optoelectronic devices, in particular to a three-body coaxial automatic coupling device for optoelectronic devices. Background technique [0002] In an optical communication system, optical feedback into a laser or amplifier will reduce the optical signal-to-noise ratio and increase the bit error rate, thereby affecting the stability of the device. The isolator is an optical passive device used in optical fiber communication to realize optical unidirectional transmission, which can effectively prevent the generation of optical feedback. In high-speed direct modulation and direct detection optical fiber communication systems, the backward transmission of light will generate additional noise, which will degrade the performance of the system, which also needs to be eliminated by isolators. Therefore, isolators play an important role in optical fiber communication and opti...
