Abstract

The invention discloses a structure of a polarization-maintaining optical hybrid device, and relates to the technical field of optical fiber communications and optical fiber amplifiers. The device comprises a first double-polarization-maintaining optical collimator, a double-pole isolator core, an optical splitter and a second double-polarization-maintaining optical collimator which are sequentially placed from left to right, and therefore the effects of integrating the functions of a polarization-maintaining wavelength division multiplexer, the functions of a polarization-maintaining isolator and the beam splitting function are realized. The structure of the polarization-maintaining optical hybrid device solves the problems that in the prior art, power consumption is high, noise is high, the size is large and the cost is high.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication and optical fiber amplifier, in particular to a hybrid integrated device including the functions of a polarization-maintaining wavelength division multiplexer, an isolator and a coupler. Background technique [0002] In the prior art, the passive components of polarization-maintaining optical fibers used in polarization-maintaining optical fiber amplifiers are generally single-function devices, which require multiple fusion splices to form functional modules of each functional device to achieve the purpose of the required system, which increases the The power loss of the system increases the noise of the system and increases the volume of the system. Contents of the invention [0003] The purpose of the present invention is to solve the problem in the prior art that a single function device needs to be connected multiple times, and propose a polarization-maintaining optical h...
