Aiming at the requirement of high-powered in optical sensing systems based on resonator, photonic crystal fiber is proposed to optimize the performance of fiber optic ring resonator (FORR). In this paper, the model of FORR is obtained after derivation, and the characteristics of FORR based on TIR-PCF, Air-core PBF and conventional fiber are analyzed, respectively. Results show that the finesse of FORR is almost the same as that of conventional fiber when the intensity loss of coupler is less than 0.1. In addition, when the fiber length is less than 20m, the sensitivity of all the three fibers is the same, and with the further increases of fiber length, the sensitivity of FORR based on Air-core PBF decreases quickly than the others.
