Abstract
An improved linear light modulator array is formed with opposing electrodes which extend away from the optic surfaces of optoelcctronic material used to form the array. A uniform electric field is created across a modulator volume, generally perpendicular to light propagation within the modulator volume. The modulator volume of an element in the array is a function of electrode length, width and separation. Additional elements are defined by additional pairs of electrodes. The geometry is obtained by cutting optoelectronic material into strips. Cut sides of the strips are metallized, one at a time, with the opposite side temporarily affixed to a carrier. Aligned trenches are cut in the metallized strips to separate electrode pairs and define array elements.
