Paper Abstract

A novel error compensation technique capable of significantly improving the gyroscope performance by reducing the polarization related bias errors of a polarization-rotating (PR) resonator is presented. It is shown that the PR-resonator has residual errors which depend on the polarization-dependent losses and coupling ratios of the resonator output coupler and on the polarization crosstalk within the ring. A bias error reduction by a factor of 50 or more is achieved by employing the technique which involves periodical switching of the resonance tracking operation between adjacent resonators.
