Abstract
An optical logic gate () comprises: first and second optical inputs () for receiving respective optical signals (A, B) and an optical output () for outputting an optical signal (P) which represents the result of applying a required logic function. The logic gate is characterized by optical combining means () for combining the optical signals to produce a corresponding combination signal whose power (P) is the combination of the powers (P, P) of the optical signals and non-linear optical means () for receiving the combination signal (P) and emitting the optical output signal (P) the logic function depending on the characteristic of the non-linear optical means wherein the characteristic is selected such that the power of the output signal is correlated to the power of the combination signal by the selected logic function.
