%X We illustrate two As2S3 waveguide  designs for four-wave mixing, which can generate 3.03 ¦Ìm mid-infrared light  from a 1.55 ¦Ìm near-infrared signal source and a 2.05 ¦Ìm pump source. Through  simulations, we verify that four-wave mixing phase-matching efficiencies up to  100% can be achieved using dispersion engineering to maintain the  dispersion at 2.05 ¦Ìm near to zero. The best conversion efficiency is ¨C10  dB. When the waveguide length is 1 cm,  the parametric conversion bandwidth is 1525 nm. We also evaluated the shift of  100% phase-matching efficiency wavelengths based upon fabrication tolerances.
