Pressure induced changes in optical pathlength are being utilized to realize a hydrophone consisting of glass fibers in a Mach-Zehnder interferometric arrangement. In our experimental setup we use single-mode fiber optical power dividers and a simple control system that maintains the polarization of both light signals so that interference with constant contrast is obtained after superposition. We use a modified phase-tracking detection system to maintain maximum interferometer sensitivity and show a design for a sensor-body with high acoustical sensitivity.
