A submicron metal grid mirror was incorporated into the structure of a silicon liquid light valve. In our experiment, a 0.5 μm-period, aluminum wire grid mirror was used in conjunction with a 90°-twisted nematic configuration. A sharp threshold with a peak-to-threshold ratio of 3:1 was experimentally observed. The threshold intensity level was tunable from 2.5 μW/cm2 to 50 μW/cm2 by changing the bias voltage from about 5 to 25 volts. These properties allow the polarization-sensitive mirror-based LCLV to be used as a non-linear SLM with applications in optical computing (bistable device) and adaptive image thresholding. The device can also be used as an interfacing device for an optical co-processor as well as for optical implementation of Hopfield-Anderson association and phase conjugation.© (1990) COPYRIGHT SPIE--The International Society for Optical Engineering.
