The nonlinear propagation of 100 fs Ti:sapphire laser pulses in a bi-refringent photonic crystal fiber is experimentally investigated. Super-continuum generation with spectra extending from 450—1050 nm was obtained and the spectra consist of distinct peaks. The spectral broadening is shown to be caused by the mechanism of spectral broadening through fission of higher-order solitons into red-shifted fundamental solitons and blue-shifted dispersion waves. The simulation of light propagation property in the waveguide can explain well the experimental results.
