An improved circulating interferometric integrated optical gyro design method by using graphene-based optical switch

Integrated optical gyroscopes have exerted a tremendous fascination on many researchers for their high sensitivity, miniature size and light weight. In this paper, an improved design method based on a graphene electro-optic switch has been presented to reduce the extra loss of the coupler. Simulation results indicate that the presented modulation method can effectively increase the input power and eliminate extra loss.
