Abstract

A spatial light modulator includes a mirror plate comprising a reflective upper surface, a louver surface having a recess in the lower surface, a first cavity having an opening on the lower surface, and a cantilever situated under the recess and connected with the lower portion of the mirror plate. The mirror plate can tilt around a hinge component extending into the first cavity. The hinge component is supported by a stationary substrate. The tilt movement of the mirror plate can be stopped when the cantilever comes to contact with a stationary object.
