给出了利用单模光纤中的交叉相位调制效应产生单周期量级光脉冲的基本思想,然后用数值方法详细分析了初始脉冲条件的改变对脉冲频谱展宽的影响,最终得到了从200THz覆盖到1000 THz的超宽带频谱,其傅里叶变换可产生单周期量级光脉冲.

Principles for monocycle-like pulse generation by crossed phase modulation in the silicon fiber are introducea in this paper. By using split-step Fourier method the effect of pulse parameters on the spectra broadening is numerically analyzed in detail. Finally, ultrabroad-band spectrum ranging from 200 to 1000 THz is achieved, and the Fourier transform of this spectrum can give a near monocycle optical pulse.
