Paper Abstract

A sensitive single-fiber acoustic sensor has been constructed by securing single-mode fiber to the diaphragm of an acoustic cavity. The acoustic pressure induces a birefrin-gence in the fiber and alters the state of polarization of the light. The sensor is capable of detecting a minimum pressure of 33dB re 111Pa/âœ"Hz and exhibits a sensitivity that is comparable to fiber-optic Mach-Zehnder interferometers.
