A FOG system with a high polarization extinction ratio includes an integrated optic circuit (IOC) having a waveguide array fabricated by a proton exchange (PE) process, the IOC being operatively connected for providing single mode, single polarization filtering of incident light guided from the FOG light source to the sensing loop and of the interference signal guided from the sensing loop to the detector.

Single-polarization, integrated optical components for optical gyroscopes

A single polarization active IO device includes a crystalline material substrate having an IO circuit array comprising an optical waveguide array disposed on a major surface of the substrate by a two step proton exchange (TSPE) process, and including an electrode array disposed on the major surface in juxtaposed relation with the waveguide array to provide one or more active IO regions thereon.

Low-loss proton exchanged waveguides for active integrated optic devices

An optical power star coupler includes a LiNbO.sub.3 or LiTaO.sub.3 substrate having a major surface for receiving a circuit array of one or more surface for splitters disposed thereon by a two step proton exchange (TSPE) process, in a geometric pattern to provide an N.times.M star coupler having high polarization extinction, uniform splitting ratio, and low loss.
