<p>A disclosed apparatus 10 is characterized by a guiding element 12 and a nonlinear element 30. The guiding element 12 guides optical input signals, at least one of which is phase-modulated, to an interference area 26 where such signals meet and interfere. The resulting interference signal is nonlinearly discriminated by the nonlinear element 30 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 100, 200.
