Paper Abstract

This paper reports the experimental results of PM-fiber ring resonator in resonator fiber optic gyroscope by our group in Tsinghua University. Adopting the PANDA-type and tied-type PM-fiber, the ring resonators about 12 meters length were fabricated according to the optimized parameters. Using a PZT modulator, the resonance curves and characteristics were recorded and analyzed. A Nd-YAG laser and a laser diode with fiber grating joined the system separately. Both of the lasers' linewidth is less than 200KHz and output power from fiber pigtail is more than 4 mW. We used two miniaturized bulked TiO2 crystal acousto-optical modulators as the frequency shifters of the clockwise wave and counterclockwise wave light. The experimental results were also presented.
