Paper Abstract

Integrated optics combined with micro-electro mechanical system (MEMS) technology offer enormous potential to improve sensitivity and performance capabilities of new sensors. In this paper, an analysis is carried out to find the feasibility and design concept of a Micro-Opto-Electro-Mechanical (MOEM) accelerometer consisting of integrated optic Mach-Zehnder interferometer, whose sensing arm is attached to a micromachined vibrating cantilever or a bridge. The analysis consists of determining changes in phase shift due to acceleration-induced refractive index and optical path length variation of MachZehender interferometer. A noise analysis is carried out to find the fundamental performance limit of different sensor configurations.
