Paper Abstract

Lithium niobate-based Y junction waveguide multifunction integrated optic chip (M-IOC) is one of core optic components in fiber optic gyro. Its performances have very important influences on fiber optic gyro (FOG) accuracies. Fully understanding its performances in FOG will help us to further improve fiber optic gyro performance (bias drift < 0.01°/h). The paper focuses on the studying of application features of Y-junction integrated optic chip(Y-IOC) in FOG with bias drift less than 0.01 °/h. It also describes the system test methods for checking integrated optic chip performances. Interesting research points are: Y-IOC optic technology and its application in FOG, features of Y-IOC in FOG, the corresponding test system and the matching of Y-IOC with FOG system. Research results show: Y-IOC optic performances, Y-IOC electrical characteristics, as well as the matching between electrical circuits of FOG system and electrical features of Lithium niobate- based Y junction waveguide multifunction integrated optic chip all together play very important roles in achieving high performances of FOG.
