Abstract

The invention relates to a single-wavelength optical transmitting-receiving integrated module comprising a tube housing, and a refrigeration device and a metal optical fiber assembly which are disposed in the tube housing. The optical fiber front end of the metal optical fiber assembly extends out of the tube housing through an opening on the tube housing. The optical fiber rear end of the metal optical fiber assembly is fixed to the refrigerating device. The refrigerating device is provided with a light emitting device, a light absorbing device and a photodiode detecting circuit. The light emitted by the light emitting device is injected into the rear end of the metal optical fiber assembly through a collimating lens group and is simultaneously reflected to the light absorbing device. The photodiode detecting circuit is used for subjecting the light absorbed by the light absorbing device to photoelectric conversion and outputting an electric signal. The single-wavelength optical transmitting-receiving integrated module uses a semiconductor cooler structure, enables a fiber sensing optical transmitting-receiving optical path to operate at constant temperature, and is improved in temperature performance. The focusing of the optical path is achieved by the collimating lens group so that light source energy is transmitted and received at a maximum to achieve an efficient transmitting-receiving function.

Description

technical field [0001] The invention relates to the fields of optoelectronic hybrid integrated circuits and optical fiber sensing, in particular to a single-wavelength optical transceiver integrated module. Background technique [0002] In the optical fiber sensing system, its front end needs to transmit and receive interference light with a single wavelength light source. The current classic technical solution is to realize discrete installation and connection of SLD light source and photodetector components through optical couplers. However, the optical path of this classic solution is complicated to manufacture, and the volume of the optical path system is relatively large, which limits its industrial application. With the rapid development of optical fiber sensing, it is necessary to explore and realize the integration of this part of the system into a module. Contents of the invention [0003] The purpose of the present invention is to provide a single-wavelength op...
