Observation of parametric gain due to four-wave mixing in dispersion engineered GaInP photonic crystal waveguides

[摘要]：We investigate four-wave mixing (FWM) in GaInP 1.5mm long dispersion engineered photonic crystal waveguides. We demonstrate an 11nm FWM bandwidth in the CW mode and a conversion efficiency of -24 dB in the quasi-CW mode. For picosecond pump and probe pulses, we report a 3 dB parametric gain and nearly a -5 dB conversion efficiency at watt-level peak pump powers. (C) 2011 Optical Society of America
