Abstract

A method of fabricating a spatial light modulator. The method includes forming cavities in a first substrate and fabricating electrodes on a second substrate. The method also includes bonding the first substrate to the second substrate and forming a mirror plate from a portion of the first substrate. The mirror plate has an upper surface and a lower surface. The method further includes forming a hinge coupled to the mirror plate and forming a reflective surface coupled to the upper surface of the mirror plate.
