Abstract

A single monomode fiber-optic acoustic sensor is proposed. The acoustic wave differentially changes the phase velocities of the polarization eigenmodes in a tension-coiled fiber, leading to a polarization rotation of the transmitted light. Sensitivities exceeding those of multimode fiber-optic hydrophones and ~40 times less than those of the two-fiber interferometric sensor should be realizable while environmental instability problems and the sensor complexity are significantly reduced.
