Abstract

An apparatus with first and second transparent conductive oxide layers is described. A photoconductive layer can be positioned between the first and a second transparent conductive oxide layers. The photoconductive layer can be a crystalline layer that can include bismuth silicate or other suitable materials. An electro-optical layer is positioned in contact with the photoconductive layer. In some embodiments the photoconductive layer is positionable to receive a write beam that defines a two-dimensional spatial pattern.
