Abstract

Characteristics of pulse trapping by ultrashort soliton pulse in optical fibers across zero-dispersion wavelength are analyzed both experimentally and numerically. The spectrogram of pulse trapping is observed using the technique of cross correlation frequency resolved optical gating and the phenomenon of pulse trapping is confirmed directly. The pulse trapping is numerically analyzed using the coupled strict nonlinear Schrödinger equations and the numerical results are well in agreement with the experimental ones. It is clarified that the pulse trapping occurs due to the sequential cross phase modulation by the Raman shifted soliton pulse.
