Abstract: A spatial light modulator comprising a solid state light valve comprising a high density two-dimensional array of "Kerr-cell" like pixels formed in a solid state electro-optical composition such as lanthanum modified lead zirconium titanate (PLZT). Transverse electrodes are deposited on a layer of PLZT the composition of which may provide for memory mode or non-memory mode operation. Pixels are defined in the electro-optic materials in regions between adjacent electrodes deposited on the electro-optic material. The array may be addressed optically or electronically to generate an electric field in the electro-optic material, and thus activate pixels.
