Paper Abstract

Optical parallel processor which performs cascade logic operations is newly constructed. The encoding concept using polarization state of light and the separation of the encoded light together are the key to the programmability for any logic operation. The operation kernel determines the logic operation to be executed only by spatially filtering spatially the encoded light. Real-time programmable cascade logic operations for three binary patterns have been demonstrated experimentally with the optical processor using a liquid-crystal spatial light modulator as the operation kernel. Up to five-step cascede operation is anticipated by using microchannel spatial light modulator having photomultifying capability as the polarization encoder.
