Abstract

Passive birefringence compensation using Faraday rotator and mirror combinations in Michelson interferometer systems has been shown to produce an interferometric output signal which is free of the effects of polarization induced fading. This technique promises to have a strong impact on the development of practical interferometric sensor systems, and is particularly important in the area of multiplexed sensors where the problem of polarization fading in conventional arrays is a serious technical issue. In this paper we describe various topologies for implementing passive birefringence compensation to achieve polarization independent operation in multiplexed sensor arrays. Results obtained on a time-division multiplexed system with 4 sensor elements are presented.
