Abstract

This thesis investigated the realisation of Fabry-Perot based micro-spectrometers using surface-micromachining techniques to fabricate vertically actuated suspended mirrors and fixed-fixed beams. The thesis introduces a reduced order model of the MEMS device to develop a novel micro-spectrometer design exhibiting a separate sensing structure to achieve closed-loop control using capacitive sensing. The proposed design mitigates the challenges posed by dielectric charging and pull-in limit,which degrade the performance of the device. Finally, this thesis explores the issues associated with the monolithic integration of the sensing structure and the control circuitry.
