Abstract

We propose and experimentally demonstrate a novel sensor array based on a Sagnac interferometer having a stable π/2 phase bias without the use of a 3x3 coupler. Signal processing is drastically simplified and polarization induced signal fading is eliminated by using a broadband source and a depolarizer.
