Abstract

We describe a fiber gyroscope operating at maximum sensitivity that is due to a nonreciprocal π/2 phase bias effected with a pulsed voltage applied to an electro-optic LiNbO3 channel waveguide phase shifter. With a He–Ne laser source, the noise was equivalent to a 0.1°/sec rotation, for a 10-Hz bandwidth and 2% reflectivity at each fiber–LiNbO3 interface. The phase shifters showed polarization-independent behavior that was characterized by measurements in a fiber interferometer. They were flip-chip coupled with single-mode fibers that were cemented to the channel ends to give a stable module.
