Paper Abstract

A comparative evaluation is conducted of the performance obtainable by means of (1) an all-fiber gyro based on a high-extinction polarizer, a Lyot-type depolarizer, and a conventional birefringent fiber coil, and (2) a gyro incorporating a polarizing integrated-optics chip fabricated by means of proton exchange in lithium niobate, as well as a high-birefringence fiber coil. Performance levels are obtained for the cases of both open and closed loop signal processing.
