Cross-phase-modulation (XPM) effects were investigated as a novel nondegenerate
method to control the spectrum of an optical pulse. The oscillating
substructures in the XPM spectra were measured with a high-resolution optical
spectral analysis system. The dispersion of the third-order nonlinearity was
obtained by measurement and analysis of the XPM and self-phase-modulation
spectra of the probe and pump pulses at different wavelengths.
