Paper Abstract

The resonance asymmetry in the waveguide ring resonator and its influence on the offset errors of the waveguide-type optical passive resonator gyro (OPRG) are demonstrated experimentally and theoretically. The offset errors are produced by the resonance asymmetry especially when the phase modulation spectroscopy technique is involved in the OPRG. Modulation frequencies of both the clockwise and counterclockwise lightwaves are determined to decrease the offset errors. The fundamental solution to eliminate the asymmetry influence on the OPRG is also proposed.
