A feasible program of single-polarization active resonator using hollow-core photonic crystal fiber is proposed in this paper. The basic structure of HCPCF active resonator is designed, and the influence of polarization mode dispersion on the detection accuracy is analyzed with a solution being put forward using single-polarization HCPCF. Then the cross structure of photonic crystal fiber is designed, modeled and simulated by finite element method (FEM) at the wavelength of 632.8nm, and the mode field distribution in the cross-section is obtained. By designing the core size of photonic crystal fiber properly, a polarization extinction ratio of 8.4dB is achieved; therefore single-polarization propagation can be realized in the HCPCF, resulting in suppression of polarization mode dispersion of resonator and improving the theoretical gyroscope detection limit. This research is of great guiding significance to the development of HCPCF RLG.
