An integrated electro-optic package for reflective spatial light modulators

摘要

An array of reflective LCSLM pixels is formed on the substrate with a polarizing layer positioned between the array and the light source. The overmolded housing defining the optical waveguide has a light input, a light output, and a mirror surface facing from the input to the output, and the polarizing layer is mounted such that light passing through the optical waveguide passes through it. The light sources are arranged so that light passes through the polarizing layer and the array is uniformly inspected. The light reflected from the array faces the mirror surface of the optical waveguide. The diffuser at the output forms an image plane for the reflected light. Electrical connections are made from the array to the circuit board on which the array is mounted. All components are sealed by an overmolded housing having leads formed in the housing to provide external contacts.
