Experimentally measured low propagation loss (0.4dB/cm in range 3.8-5.0μm) and dispersion engineering waveguide allowed us achieving ~5mW useful average power.application/pdfen-AU© OSA 2018Experimental demonstration of mid-IR Octave spanning supercontinuum generation in low loss silicon- germanium waveguide201810.1364/OFC.2018.M2J.32019-11-25
