| 摘 要： | 在色散位移光纤中，研究了三阶色散影响下同相和反相二阶孤子之间的互作用，分析了同相和反相二阶孤子对衰变后时域波形和频域频移的变化，发现三阶色散使二阶孤子分裂出一大一小两个不同振幅的基阶孤子，并彼此分离，但孤子对中心频率频移量却减小。通过采用非线性增益控制的方法可以有效抑制二阶孤子间的互作用，使孤子保型传输而不发生衰变。同时通过周期性改变三阶色散系数，可以减小三阶色散的不利影响，抑制孤子中心频率的频移，使孤子对不偏离原来时间槽，稳定孤子传输。 |

| Abstract: | Under the influence of third-order dispersion, the interaction of second order solitons in dispersion-shifted fibers was investigated numerically. The characteristics of second order solitions split was researched in the time and frequency domain. It is found that under the influence of third-order dispersion, two second order solitons are both split and apart from each other. But the frequency shift is decreased. A nonlinear gain and periodical alternation of third-order dispersion can be used to effective... |
