A fiber-optic acoustic pressure sensor based on a large-area nanolayer silver diaphragm is demonstrated with a high dynamic pressure sensitivity of 160nm/Pa at 4 kHz frequency. The sensor exhibits a noise limited detectable pressure level of 14.5μPa/Hz1/2. Its high dynamic pressure sensitivity and simple fabrication process make it an attractive tool for acoustic sensing and photo-acoustic spectroscopy.
