Abstract
The optical fiber is an ideal tool for studying the dynamics of nonlinear interaction between pulses, and here in particular the wavelength-shift induced by cross-phase modulation (XPM) in an ultrashort pulses pump-probe configuration. So far, significant wavelength shifts in the visible and near-infrared have been demonstrated and modeled [1]. To demonstrate further the potentiality for all-optical switching and mux/demux applications, it is relevant to quantify the importance of the probe time-profile reshaping. To the best of my knowledge the present contribution is the first to present and discuss the autocorrelation traces of blue- and red-shifted femtosec-ond probes. In comparison to the picosecond regime, some particularities of the variations of the wavelength conversion as a function of the initial relative time-delay are depicted and interpreted in terms of pulse trapping across the fiber zero-dispersion wavelength (ZDW) [2].
