摘要： The increasing demand in spectroscopy and sensing calls for infrared (mid-IR) light sources. Here, we theoretically investigate nonlinear wavelength conversion of Ge$_{28}$Sb$_{12}$Se$_{60}$ chalcogenide glass waveguide in the mid-IR spectral regime. With waveguide dispersion engineering, we predict generation of over an octave wavelength (2.8 μm-5.9 μm) tuning range Raman soliton self-frequency shift, over 2.5 octaves wavelength cover range supercontinuum (1.2 μm-8.0 μm), as well as single soliton Kerr comb generated in suspended Ge$_{28}$Sb$_{12}$Se$_{60}$ waveguide. Our findings evidenced that Ge$_{28}$Sb$_{12}$Se$_{60}$ chalcogenide glass waveguides can simultaneously satisfy the generation of Raman soliton self-frequency shift, supercontinuum spectrum, and Kerr frequency comb generation through dispersion engineering towards mid-IR on chip.
