Abstract
A method of making a linear light valve array having a plurality of transversely driven, discretely addressable, electro-optic gates, includes the steps of (i) cutting parallel grooves of uniform depth to form a land region on a wafer of electro-optical material; (ii) holding a stencil having reference and address electrode patterns over the land region and groove portions of the wafer; and (iii) depositing conductive material through the stencil to form address and reference electrodes on opposing side walls of the land region. Linear and two-dimensional modulator devices made by such method are disclosed also.
