Abstract
An electro-optic medium, useful for image processing, is formed by creating a distribution of deep impurity levels over essentially all the lateral extent of a multilayer heterostructure. This treatment renders the heterostructure semi-insulating, and as a consequence, individual image-resolution elements are isolated. Described is an optical system comprising such an electro-optic medium.
