Passive stabilization of temperature dependent polarization errors of a polarization-rotating resonator fiber optic gyroscope

摘要

The polarization-rotating resonator was developed to reduce temperature dependent polarization errors of a resonator fiber optic gyroscope for navigation-grade applications. Residual temperature dependent fluctuation of the symmetry of the resonance features limits the gyroscope performance. We present a fabrication technique, involving white-light interferometry, that yields a passive stabilized resonator. Experimental results show greatly improved resonator thermal stability.
