Module for optical parallel logic using bistable optically addressed ferroelectric spatial light modulators

摘要

The optical module described is designed to perform cascadable optical parallel logic operations, using 2-D binary registers consisting of two optically addressed ferroelectric liquid crystal spatial light modulators. The high contrast ratio and bistability of the device are particularly useful in the construction of optical logic units. This paper illustrates the cascading abilities of such a device in performing a parallel optical XOR logic operation.
