Paper Abstract

Polarization fluctuation caused by polarization coupling in polarization maintaining fiber (PMF) resonator is one of the major noise sources in resonant fiber optic gyroscope. Polarization axis 90-degree docking is an effective way to overcome the polarization fluctuation, but the 90-degree docking error has a major affect to the gyroscope noise suppression effect. In this paper, a fiber Michelson interferometer testing system of polarization coupling in doublecoupler polarization maintaining fiber resonator based on white-light interferometer is designed to realize 90-degree docking error control and obtain a good result of 0.37 degree experimental docking error. Then the detection method of sawtooth scanning is used to analyze the resonance characteristics and polarization characteristics of double-coupler polarization maintaining fiber resonator experimentally and obtains the response curve with 24 finesse and 179.65 degree phase interval of the two polarization eigenstates.
