Phase sensitive parametric interactions in a $Ga_{0.5}In_{0.5}P$ photonic crystal waveguide

摘要

We report phase sensitive amplification in a 1.5mm long, $Ga_{0.5}In_{0.5}P$dispersion engineered photonic crystal waveguide which has a flatteneddispersion profile. A signal degenerate configuration with pulsed pumps whosetotal peak power is only 0.5W yields a phase sensitive extinction ratio of10dB.
