  • Patent number: 6222667
    Abstract: A two-dimensional light valve array comprising a pattern of reduced electrode spacing solid state light valves formed using semiconductor processing techniques, and a method of making same. The electrodes are recessed into channels in an electro-optic substrate, such as lanthanum modified lead zirconate-titanate (PLZT). A first set of electrodes are deposited in a comb-shaped configuration into parallel and orthogonal channels etched into the PLZT substrate. A second set of deposited electrodes are bands running in alternating channels between the teeth of the first set of electrodes. An insulating material isolates the two sets of electrodes. An applied voltage between the electrodes induces bi-refringence in the PLZT and affects light transmissivity through the light valve at that location. The array is activated electronically by means of matrix addressing and controlled by means of a microcomputer and appropriate software.
