摘要 研究了高阶效应影响下,色散位移光纤中二阶孤子间的相互作用,分析了二阶孤子对衰变后时域波形的变化.研究表明,引入非线性增益控制和谱共轭相结合的方法可以有效抑制孤子间互作用,实现波形失真的补偿,并且孤子脉冲不偏离原来的时间槽. Under the influence of higher-order effects, the interactions between second order solitons in dispersion-shifted fibers are investigated numerically. The characteristics of second order solitions split have been studied in the time domain. A nonlinear gain and spectral phase conjugation (SPC) can be used to effectively suppress soliton interactions and compensate for waveform distortion.
