Abstract
We describe a novel optical acoustic detector based on a bias-controlled fiber Fabry-Perot interferometer. Broad bandwidth as 15 MHz similar to a few GHz and higher sensitivity than that of conventional systems were demonstrated. The minimum detectable phase was 4x10(-8) rad/Hz(1/2), which was 3 times larger than the quantum-limited value.
