Interferometric Fiber Optic Gyroscope Using a Novel 3x3 Integrated Optic Polarizer/Splitter

Abstract
A Ti:LiNbO3 3x3 directional coupler, acting as both polarizer and 3db splitter, with a phase modulator has been incorporated in an interferometric fiber optic gyroscope. A random walk performance of 1x10^-20h has been demonstrated.
