Abstract

A mirror, or an array of mirrors, for use in a micro-electro-mechanical system (MEMS) optical device. The mirror includes a mirror substrate having a loss-reducing layer located over a first or second side thereof, and a light reflective optical layer located over the loss-reducing layer. The inventive mirror reduces undesirable Fabry-Perot interferrometric optical loss through minimizing the extent of multiple reflections within the MEMS mirror substrate.
