Abstract

Field distributions and electro-optic effects in ceramic bulk and thin film materials have been calculated by using Green's function and summary representation methods. The specific problems that have been analyzed include displays and spatial light modulators with 1) multiple interdigital planar electrodes on one side of the sample, 2) multiple interdigital planar electrodes on both sides of the sample, with or without misalignment of the electrodes on opposite sides, 3) optimization of the electro-optic effect by optimizing the electrode gap, width, number of electrodes, and sample thickness, 4) electrooptic effects with transparent electrodes, and 5) electro-optic effects in devices that have been coated with a buffer or capping thin film layer of various dielectric constants. Many interesting new effects have been predicted by our model and agree very well with our experimental observations and measurements, including field enhanced electro-optic effects in PLZT bulk and thin film display with a buffer and/or a capping layer.
