Supercontinuum generation in dispersion engineered highly nonlinear (gamma = 10 /W/m) As2S3) chalcogenide planar waveguide

Opt Express. 2008 Sep 15;16(19):14938-44. doi: 10.1364/oe.16.014938.


We demonstrate supercontinuum generation in a highly nonlinear As(2)S(3) chalcogenide planar waveguide which is dispersion engineered to have anomalous dispersion at near-infrared wavelengths. This waveguide is 60 mm long with a cross-section of 2 mum by 870 nm, resulting in a nonlinear parameter of 10 /W/m and a dispersion of +29 ps/nm/km. Using pulses with a width of 610 fs and peak power of 68 W, we generate supercontinuum with a 30 dB bandwidth of 750 nm, in good agreement with theory.
