Optical fiber ring resonator composed of an ordinary single-mode fiber for resonator fiber optic gyros: experiment

摘要

A stable ring-resonator has been fabricated by an ordinary single mode fiber. Combination of a twisted-fiber loop and a coiled-fiber $lambda@/2 element makes the resonance-dip- separation fixed to be $pi to reduce the polarization-fluctuation induced drift in Resonator-FOGs.
