Compared with using quantum effect to realize electromagnetically induced transparency (EIT), the method of using microring resonators to achieve coupled resonator induced transparency (CRIT) has some significant advantages, such as all solid state, feasibility in fabrication and application, etc. Recently, there are some explorations on using CRIT to enhance the sensitivity of optical gyroscopes, and realize micro waveguide gyroscopes. In this thesis, using the transfer matrix method, CRIT in a double-parallel-microring structure is analyzed, and the influence of the parameters of the structure on the transmission characteristics of it is calculated and analyzed. The conditions to realize CRIT is given. The slow-light effect in the structure is analyzed. Based on the above work, the mechanism for using CRIT to enhance gyroscope sensitivity is discussed. The double-parallel-mirroring structure is improved to be used as the gryoscope's sensitive part. Its transfer matrix when rotating is derived, and the Sagnac phase shift of the whole structure is calculated. Analysis demonstrates that this CRIT structure can enhance the measurement sensitivity of rotational velocity.
