Abstract

A transmissive beam steering aperture includes a common superstrate provided from an optical material and having first and second opposing surfaces with at least one of the first and second surfaces having an electrode coating provided thereon to provide the at least one surface as a common electrode surface and having a first plurality of electrically isolated common electrodes. One or more electrode containing substrates is disposed over respective ones of the first plurality of electrically isolated common electrodes to form one or more one liquid crystal (LC) cells. In one embodiment, the transmissive beam steering aperture is used as an aperture in an optical phased array.
