Abstract

We describe a novel optical acoustic detector based on a bias-controlled fiber Fabry-Perot interferometer. Broad bandwidth as 15 MHz ~ a few GHz and higher sensitivity than that of conventional systems were demonstrated. The minimum detectable phase was 4 x 10^-8 rad/Hz^1/2, which was 3 times larger than the quantum-limited value.
