Abstract

Micro-electro-mechanical systems (MEMS) are used in applications ranging from consumer electronics to medical diagnostics. Alternatively, optical sensors offer low-noise, remote read-out via optical fiber, and are insensitive to electromagnetic interference. We demonstrate micro-opto-mechanical sensors (MOMS) in siliconnitride photonic technology. Experimental results and design trade-offs of pressure, sound, and ultrasound sensors are reported. Transparency for visible light offers prospective applications in life sciences, such as photo-acoustics.
