title: Phase-sensitive four-wave mixing interferometer.
abstract: A nonlinear interferometer is constructed using a dual-pump, dual-signal four-wave mixing (FWM) process. The generated idlers are categorized into phase-insensitive and phase-sensitive (PS) outputs according to whether the power is sensitive to the phase difference of the input signals. The PS idlers are obtained from the interference of the primary idlers and are regarded as the FWM interferometer output. Potential applications include photonic exclusive-NOR and exclusive-OR operations, photonic correlators, and photonic microwave filters.
