Abstract
A liquid crystal on silicon (LCOS) device includes a silicon substrate and a pair of electrodes including an upper and a lower electrode. The lower electrode is mounted to the silicon substrate and includes a two dimensional array of pixels extending in both a first and second dimension. LCOS device also includes a liquid crystal layer disposed between the upper and lower electrodes and configured to be driveable into a plurality of electrical states by drive signals provided to the pixels of the lower electrode. The pixels are rectangular in profile having longer sides in the first dimension than in the second dimension. Further, the two dimensional array includes a pixel pitch that is greater in the first dimension than in the second dimension.
