Spectrotemporal similarity and self-imaging of nonlinear-dispersive similariton

Using spectral-interferometry for short pulse complete characterization, we studied the similariton generated in single-mode fiber without gain due to the combined impacts of nonlinearity and dispersion. The nonlinear-spectronic nature of such a similariton, with the key specificity of linear chirping, leads to its self-spectrotemporal imaging, important for applications to signal analysis - synthesis problems in ultrafast optics.
