Spectrograms corresponding to evolutions in Fig. 2 (numerical modeling).
(a) soliton configuration. (b) shock wave configuration. The spectrograms represent the spectra over gated time intervals and are computed at the output of each fibers (for the evolution along the fibers, see the additional multimedia files). ZDW: zero-dispersion wavelength.
