Abstract

We propose highly nonlinear slot waveguides with flat and low dispersion over a wide wavelength range. Si nano-crystal and chalcogenide glass are considered as slot materials. Over a 244-nm bandwidth, dispersion of 0±0.16 ps/(nm∙m) is achieved in a silicon nano-crystal slot waveguide, with a nonlinear coefficient of 2874 /(W∙m). The As2S3 slot waveguide exhibits dispersion of 0±0.17 ps/(nm∙m) over a bandwidth of 249 nm, with a nonlinear coefficient 16 times larger than that of As2S3 rib waveguides and a nonlinear figure of merit three times larger than that of Si strip waveguides.
