提出了一种新的增强型孤子效应脉冲压缩方法 ,即让两个中心波长比较接近的脉冲在光纤反常色散区共同传输 ,与传统的单脉冲压缩相比 ,交叉相位调制可使得双脉冲的孤子效应压缩得到显著增强 .计算表明 ,交叉相位调制不仅能有效地提高脉冲压缩比 ,而且能大幅度缩短脉冲压缩所需的光纤长度 .还进一步就脉冲离散效应、Raman自散射效应、以及初始输入脉宽不匹配等因素对脉冲压缩的影响进行了详细的计算和分析 .该方法对于克服传统的单脉冲压缩方法中输入脉冲峰值功率不够高的困难是非常有效的 .
A new enhanced soliton-effect pulse compression method is proposed, in which two pulses with the same center wavelength are transmitted together in the anomalous dispersion region of the fiber. Compared with the traditional single-pulse compression, the cross-phase modulation can make the double-pulse soliton The results show that the cross-phase modulation can not only effectively improve the pulse compression ratio, but also greatly shorten the length of the fiber needed for pulse compression.Furthermore, the pulse dispersion effect, Raman self-scattering effect, and the initial input pulse Width mismatch and other factors on the pulse compression of a detailed calculation and analysis.This method is very effective for overcoming the traditional single-pulse compression method is not high enough input pulse peak power is very high.
