Abstract
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.
