The fiber ring resonator (FRR) is the key component of resonator fiber optic gyros (R-FOGs). The configuration of a novel hollow core photonic bandgap fiber (HC-PBF) ring resonator is proposed based on the usage of micro-optical structure. The normalized transfer function of such kind of FRR is derived, and the effects of different FRR parameters' on the resonant depth, resonant finesse and sensitivity limited by the shot noise of the detector are simulated. The laboratory sample of integrated HC-PBF ring resonator is fabricated and tested experimentally and the optimal scheme is proposed based on the acquired test data. The experimental setup and results verify the feasibility of the micro-optical coupling structure used in the HC-PBF ring resonator and also support the integration and miniaturization of R-FOGs composed of HC-PBFs.
