ABSTRACT:
A disclosed apparatus comprises a guiding element and a nonlinear element. The guiding element guides optical input signals, at least one of which is phase-modulated, to an interference area where such signals meet and interfere. The resulting interference signal is nonlinearly discriminated by the nonlinear element to produce an optical output signal that can be amplitude- or phase-modulated according to the phase modulation of the input signals. The invention also includes related methods and photonic logic gates.
