Paper Abstract

The random fluctuation in the input polarization to an interferometric optical fiber sensor can result in not only the variation of the visibility but also the generation of excess phase noise in the output. In this paper, the relationship between the visibility and polarization-induced phase noise coefficient is described and theoretically confirmed. The use of polarization diversity receivers (PDR) to reduce phase noise is theoretically and experimentally demonstrated. The result shows that the PDR that improves the visibility can reduce the polarization-induce phase noise and the signal can be correctly demodulated.
