RESUMO
We demonstrate coherent supercontinuum generation spanning over an octave from a silicon germanium-on-silicon waveguide using â¼200fs pulses at a wavelength of 4 µm. 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.
