Paper Abstract

A novel pressure sensor with a mesa structure diaphragm based on microelectromechanical systems (MEMS) techniques is presented. The operating principle of the MEMS pressure sensor is expatiated by the Fabry-Parot (F-P) cavity model and the relation between pressure and interference light intensity is deduced in the sensor. The mechanical model of the mesa structure diaphragm is validated by simulation, which declares that the mesa structure diaphragm is superior to the planar one on the depth of parallelism. Experimental system is also introduced.
