Abstract
Coupled resonant optical waveguide (CROW) gyroscope is an important type of integrated optical gyroscope based on Sagnac effect. However, the traditional CROW design method relying on empirical adjustment of parameters is deficient in achieving its best capability and the poor Sagnac effect of micro-scale devices leads to unsatisfactory performance of integrated devices. Therefore, the present study proposes a new approach to design CROW gyroscope by applying intelligent optimization algorithm (PSO: particle swarm algorithm) to design CROW gyroscope. Three aspects of work will be explored: Firstly, a new evaluation index is proposed to evaluate the efficiency of integrated optical gyroscope area utilization (EGA). Secondly, The performance limits for different losses and the accuracy limits and related parameters that can be achieved by increasing the resonator area at different losses are also explored. Finally, we designed theoretical performance (The angle random walk) up to 29.1𝑑𝑒𝑔/√ℎ and only 1mm × 1mm in size.
