Optical parallel logic gate using spatial light modulators with the Pockels effect

This paper describes a new optical gate for logical processing in parallel. The gate consists of two spatial light modulators which spatially modulate a lightwave by the longitudinal electrooptic or Pockels effect. The gate can perform in parallel all sixteen logic functions of two binary variables in both the bright-true logic and the dark-true logic. The gate has the capability of operating on large arrays of binary variables.
