） Abstract： A proposal for broadband wavelength conversion using four-wave mixing is presented based on a slot waveguide with silicon nanocrystals (Si-nc's) as the optical nonlinear material
The dispersion of the waveguide is engineered to realize a flat dispersion as well as a small effective mode area for better nonlinear interaction by optimizing the waveguide dimensions
The conversion performance is synthetically analyzed and numerical results show that a bandwidth of over 400 nm and an efficiency of -2
38 dB can be achieved using a pump power of 150 mW in a 4-mm-long Si-nc slot waveguide
