Phase-sensitive amplification of light in a X(3) photonic chip using a dispersion engineered chalcogenide ridge waveguide

We report phase-sensitive amplification of light using x(3) parametric processes in a chalcogenide ridge waveguide. By spectrally slicing pump, signal and idler waves from a single pulsed source, we are able to observe 9.9 dB of on-chip phase-sensitive extinction with a signaldegenerate dual pump four-wave mixing architecture in good agreement with numerical simulations.
