Abstract
The resonant micro-optic gyroscope (RMOG) is an attractive candidate for inertial rotation sensors requiring small, light and robust gyros. A high-performance RMOG needs a low-loss and high finesse waveguide-type ring resonator (WRR). Two general configurations of the WRRs which are made of Ge-doped silica core waveguides based on plasma enhanced chemical vapor deposition including the reflector-type and the transmitter-type are introduced. The reflector-type WRR with a length of 7.9 cm and a diameter of 2.5 cm has a finesse of 196.7 and a resonant depth of 98%. In addition, it’s pigtailed with single-polarization fiber to reduce the polarization error. The transmitter-type WRR with a length of 15.9 cm and a diameter of 5.06 cm has a finesse of 128 and a resonant depth of 95%. The waveguide loss low as 0.007 dB/cm has been measured, leading to the shot-noise limited sensitivity of 1.0°/h when the average optical power at the input of the photodetector is 1 mW and the detecting bandwidth is 1 Hz.
