Abstract
A liquid crystal on silicon device is described. The liquid crystal on silicon device includes a plurality of mirror electrodes, a transparent electrode, a liquid crystal material, and a plurality of microlenses. The plurality of mirror electrodes are arranged periodically to form an array of pixels, each pixel included in the array of pixels configurable to reflect incident light. The transparent electrode is optically aligned with the plurality of mirror electrodes. The liquid crystal material is disposed between the transparent electrode and the plurality of mirror electrodes. The plurality of microlenses are optically aligned with the plurality of mirror electrodes. Each microlens included in the plurality of microlenses is positioned to focus the incident light on a respective one of the plurality of mirror electrodes.
