Femtosecond pulse propagation at λ=802 nm; in microstructured fiber (MF) with zero-dispersion wavelength at 780 nm is studied experimentally and numerically. The temporal and spectral distributions of the femtosecond pulse in MF are demonstrated by using a grating-eliminated no-nonsense observation of ultrafast incident laser light e-fields technique. Soliton fission is directly observed in the experimental results. The simulation of soliton evolution with the propagation distance in time and frequency domain is conducted.
