An optical device having a high reflector tunable stress coating includes a micro-electromechanical system (MEMS) platform, a mirror disposed on the MEMS platform, and a multiple layer coating disposed on the mirror. The multiple layer coating includes a layer of silver (Ag), a layer of silicon dioxide (SiO<SUB>2</SUB>) deposited on the layer of Ag, a layer of intrinsic silicon (Si) deposited on the layer of SiO<SUB>2</SUB>, and a layer of silicon oxynitride (SiO<SUB>x</SUB>N<SUB>y</SUB>) deposited on the layer of Si. The concentration of nitrogen is increased and/or decreased to tune the stress (e.g., tensile, none, compressive).
