Design and Analysis of Dispersion Engineered Rib Waveguides for On-Chip Mid-Infrared Supercontinuum

A highly nonlinear optical rib waveguide structure with various core-shape profiles in As2Se3 chalcogenide glass has been reported for on-chip supercontinuum sources in the mid-infrared region. The reported rib waveguide structure offers the ultrabroadband mid-infrared spectral broadening spanning 1000–10 900 and 1000–11 880 nm for rectangular-core and triangular-core profiles, respectively, using 497-fs hyperbolic laser pulses of a peak power of 6.4 kW at 2800 nm. To the best of our knowledge, such an ultrabroadband supercontinuum spectrum has been reported for the first time using the triangular-core profile of waveguide in chalcogenide glass. The reported rib waveguide devices generating mid-infrared supercontinuum will be applicable in various important applications such as security, noninvasive early disease detection, defense, and spectroscopy.
