外文摘要：The increasing demand in spectroscopy and sensing calls for infrared(mid-IR)light sources.Here,we theoretically investigate nonlinear wavelength conversion of Ge28Sb12Se60 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 Ge28Sb12Se60 waveguide.Our findings evidenced that Ge28Sb12Se60 chalcogenide glass waveguides can simultaneously satisfy the generation of Raman soliton self-frequency shift,supercon-tinuum spectrum,and Kerr frequency comb generation through dispersion engineering towards mid-IR on chip.
