ABSTRACT:
An optical logic gate (10) comprises: first and second optical inputs (11, 12) for receiving respective optical signals (A, B) and an optical output (15) for outputting an optical signal (Pout) which represents the result of applying a required logic function. The logic gate is characterized by optical combining means (13) for combining the optical signals to produce a corresponding combination signal whose power (Pi) is the combination of the powers (PA, PB) of the optical signals and non-linear optical means (14) for receiving the combination signal (Pi) and emitting the optical output signal (Pout) 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.
