Paper Abstract

An optical fiber PZT cylinder phase modulator is frequently used in an optical fiber interferometric sensor for demodulating sensing signals. In this paper, we combine the piezoelectric equations and the fiber phase shift relations to deliver a thorough description of the phase response of the optical fiber PZT cylinder phase modulator. We also design an experiment to verify our derivation. The result is quite compatible with published data.
