ABSTRACT:
A spatial light modulator comprises an array of micromirror devices each of which has a reflective and deflectable mirror plates. The mirror plates are moved between an ON and OFF state during operation, wherein the OFF state is a state wherein the mirror plate is not parallel to the substrate on which the mirror plate is formed. The micromirror device may have an ON state stopper for limiting the rotation of the mirror plate at the ON state angle, but does not have an OFF state stopper. The non-zero OFF state is achieved by attaching the mirror plate to a deformable hinge held by a hinge support that is curved at the natural resting state.
