Summary: 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 SiO2 gets superimposed on to the exit pulse in the normal dispersion regime of solid fiber for lengths exceeding 6LDLNL. The super continuum spectrum from hollow Noble-gas-filled fibers shows remarkably deep modulations.
