The generation of an optimal ultra-broadband supercontinuum (SC) is numerically investigated in tapered and dispersion-managed (DM) silicon nanophotonic waveguides. DM waveguides are structures showing a longitudinally dependent group velocity dispersion that results from the variation of the waveguide width with the propagation distance. A genetic algorithm is used to find the best dispersion map. This allows for the generation of highly coherent supercontinuums that span over 1.14 octaves…
