Wideband Mid-Infrared Supercontinuum Generation Using Inverse Tapered Silicon Nitride Waveguide

In this paper, we have proposed a novel supercontinuum (SC) light source which can emit a broadband spectrum in the mid-infrared (MIR) region ranging from 760 nm to 6675 nm. The proposed 3-mm-long inversely tapered shaped waveguide is optimized numerically adopting the parabolic tapering approach. Structurally, the waveguide is comprised of silicon nitride (Si3N4) as core mat...
