Problem StatementOptical communication systems require variable attenuators and shutters to control individual light beams. This project explores the use of thermomechanical actuation to create a MEMS variable optical attenuator (VOA) and its associated control circuitry. This device should incorporate a continuously adjustable element that can interrupt a light beam in a fiber optic network, thereby adjusting power level of the signal. The chip's design and packaging should therefore allow for connection with optical fibers.
