Nonlinear-dispersive similariton of passive fiber

Abstract

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