【Abstract】 With the aid of computer simulation, we study energy spectrum erolntion of the fundamental solitons propagating in fibers, caused by Raman self-pumping. We find that the self-frequency shift effect will be accompanied with bandwidth change and energy spectrum distortion of the solitons whose durations are shorter than sub-picosecond.更多还原
