Integrated electro-optic package for reflective spatial light modulators

Abstract

An array of reflective LCSLM pixels formed on a substrate with a light polarizing layer positioned between the array and a light source. An overmolded housing defining an optical waveguide having a light input, a light output, and a mirrored surface directing light from the input toward the output, the polarizing layer being mounted to allow light passing into the optical waveguide to pass therethrough. The light source provided to direct light through the polarizing layer and evenly illuminate the array. Light reflected from the array is directed onto the mirrored surface of the optical waveguide. A diffuser at the output forms an image plane for the reflected light. Electrical connections are made from the array to a circuit board on which it is mounted. All components are encapsulated by the overmolded housing, having leads formed in the housing to provide external contacts.
