title: Supercontinuum generation in the mid-infrared from a dispersion-engineered As2S3 glass rib waveguide.
abstract: We report the generation of a mid-infrared supercontinuum created by ≈7.5 ps duration pulses at 3260 nm passing through a dispersion engineered As(2)S(3) rib waveguide. The threshold for a 6.6 cm long waveguide was around 800 W and at 1700 W the spectrum extended from ≈2.9-4.2 μm and was limited on the long wavelength side by absorption in the cladding of this particular waveguide.
