We demonstrate coherent supercontinuum generation spanning over an octave from a silicon germanium-on-silicon waveguide using similar to 200 fs pulses at a wavelength of 4 mu m. The waveguide is engineered to provide low all-normal dispersion in the TM polarization. We validate the coherence of the generated supercontinuum via simulations, with a high degree of coherence across the entire spectrum. Such a generated supercontinuum could lend itself to pulse compression down to 22 fs. (C) 2020 Optical Society of America
