We demonstrate soliton-effect pulse compression in mm-long photonic crystal waveguides resulting from strong anomalous dispersion and self-phase modulation. Compression from 3ps to 580fs, at low pulse energies(~10pJ), is measured via autocorrelation.
We report highly efficient four wave mixing in InGaP photonic crystal waveguides. Conversion efficiencies of -52.5dB for two ~1mW CW signals, and -38.8dB for a 1.4mW CW probe and a 14.4mW pulsed pump were demonstrated.
We report a large third order nonlinear response in an InGaP photonic crystal waveguide. The nonlinearity is enhanced by a resonance effect due to the waveguide end facet reflectivities and the large group index.
