Abstract

A liquid-crystal optical modulator called the 2DPL-LCLM is designed to perform 2D pattern-logic operations that can be used in optical digital computations. The structure includes a layer with an array of patterned transparent electrodes between the dielectric mirror and the light-blocking layer. The utility of the device is demonstrated with an application to truth-table look-up symbolic substitution in digital optical computing that demonstrates resilience to the pattern-shift of the technique
