A Schottky-diode-based liquid crystal light valve (LCLV) was assembled and tested. Two configurations were designed: a double Schottky layer structure and a single Schottky configuration. The double Schottky configuration is designed to allow a balanced AC to flow through the device, thus minimizing the LC decomposition that occurs due to DC flow. Both structures have been fabricated and tested. The front Schottky contact consists of a metal matrix of platinum islands (17 × 17 μm2) separated by chemical-vapor-deposited oxide (3-μm2 channels). The I-V characteristics of the Pt-nSi Schottky diode fabricated in the metal-matrix configuration are shown. Preliminary results showed a resolution of 10 line pairs/mm and a contrast ratio of 10:1 at the response time of the liquid crystal (≅20 ms).
