Multi-octave mid-infrared supercontinuum generation in dispersion-engineered AlGaAs-based strip waveguides
We propose and numerically investigate mid-infrared supercontinuum generation in dispersion-engineered Al<inf>0.18</inf>Ga<inf>0.82</inf>As-based strip waveguides. An ultra-board supercontinuum ranging from 2 to 15.9 µm is obtained when pump pulses with center wavelength of 4.1 µm and peak power of 3.35 kW are used.
