The micro mirror is a versatile MEMS device which is mainly used for light deflection and control. The micro mirror state is controlled by applying voltage between the electrodes around the mirror arrays. Electrostatic actuation is the methodology used for precise control of mirrors. We have designed arrays of electrode of different dimension which produces different tilting angle. We have analyzed that when aspect ratio of fixed electrode is increased corresponding tilting angle get increased linearly. Also, analyzed that when applied voltage increases corresponding tilting angle gets increased. The micro mirror is designed and the deflection value is simulated by using COMSOL Multi physics Software.
