An optically addressable light valve comprises a first transparent conductor layer, a layer of liquid crystal, and a photoconductor comprising an ultrawide band gap (UWBG) semiconductor. The liquid crystal is between the first transparent conductor layer and the semiconductor photoconductor. The optically addressable light valve is configured to apply a voltage across the liquid crystal and the UWBG semiconductor. A second transparent conductor may be formed in the UWBG semiconductor in some configurations, and the voltage may be applied across the first and second transparent conductor.
