We show through numerical simulations that silicon waveguides can be used to create a supercontinuum extending over by launching femtosecond pulses as higher-order solitons. The physical process behind continuum generation is related to soliton fission, self-phase modulation, and generation of Cherenkov radiation. In contrast with optical fibers, stimulated Raman scattering plays little role. As low-energy pulses and short waveguides () are sufficient for continuum generation, the proposed scheme should prove useful for practical applications.
