A hollow core photonic band gap fiber ring resonator based on micro-optical structure is proposed. The normalized transfer function model of this resonator was established, and the relationship between the parameters of the micro-optic structure and the characteristics of the resonator and the ultimate sensitivity of the gyro was simulated and analyzed. The experimental samples based on hollow-core photonic band-gap fiber resonator with micro-optical structure were developed, and the performance of the sample was tested. On this basis, the next optimization scheme was proposed. The results provide theoretical and experimental basis for further study of resonant hollow-core photonic band-gap fiber optic gyro based on micro-optical structure.
