ABSTRACT:
A spatial light modulator including a thin layer of solid-state electro-optical material having parallel, opposite first and second surfaces, an elongated first electrode disposed on the first surface and a plurality of spaced, elongated second electrodes disposed on the second surface and generally perpendicular to the first electrode. The layer of solid-state electro-optical material has a thickness in the range of approximately 5 to 15 microns, and is composed of PLZT. In one embodiment, a plurality of thin regions of insulator are disposed on the first surface between portions of the first electrode and the electro-optical material.
