• We examine effects of higher order dispersion and optical non-linearity, including linear attenuation on intense short pulses propagating along solid and Noble-gas-filled wave-guides. In order to simulate realistic pulse and spectral shapes, we have taken into account quadratic and cubic dispersion as well as Raman (solid wave-guide) and `shock'nonlinear terms in the generalized Schrodinger equation of propagation. The phonon oscillation corresponding to 13.3 THz in SiO_2 gets superimposed on to the exit pulse in the normal dispersion regime of solid fiber for lengths exceeding √<6L_DL_<NL・>> The super continuum spectrum from hollow Noble-gas-filled fibers shows remarkably deep modulations
