Interference-based logic gates

Interference-based logic gates serve as a basis for photonic computers intended (as distinct from quantum computers) for the same class of problems as electronic computers and making it possible to increase performance irrespective of the limitations inherent in electronic technologies. The proposed interference-based logic gates represent a complete basic functional set. They meet the requirement for the identity of intensity values corresponding to logic constants “0” and “1”. A method for intensity scaling is developed. Parameters of interference-based logic gates are estimated, and the advantages of such gates over their electronic counterparts are demonstrated.
