Abstract

This paper presents numerical simulations of the sensitivity to rotation of a coupled resonant optical waveguide (CROW) gyroscope consisting of multiple rings with couplings periodically modulated strong and weak around the central ring. Two variations of this general configuration are considered: namely, CROWs with either two separate input/output waveguides or a single input/output waveguide, and CROWs in which the rings are folded on top of each other. The single-waveguide folded CROW gyroscope is found to exhibit the highest sensitivity, and this maximum sensitivity is slightly lower than the maximum sensitivity of a single-resonator gyroscope.
