We predict a new regime of coherent supercontinuum generation in photonic-crystal fibers based on few-cycle higher order soliton dynamics. Instead of using the standard soliton fission process, we exploit dramatic shock formation dynamics of a higher-order soliton, which completely converts the input solitonic radiation to different wavelength regions in the normal dispersion regime. This enables the transfer of energy to coherent radiation in the visible as well as the ultraviolet spectral range. The scheme is simple, very effective and completely deterministic, which suggests the possibility to compress the pulses down to the sub-cycle level and thus hold a new way to directly generate attosecond pulses well outside the vacuum ultraviolet. We present numerical simulations for commercially available fibers with realistic pulse parameters and present preliminary experimental results, supporting the theoretical prediction.
