论文摘要
使用广义的非线性schrödinger方程，我们研究了三阶分散，自我静止和拉曼诱导的频率转移的效果如何影响高阶的流氓波。我们观察到，每个效应都会分解降低其组成的基本部件的高阶流氓波，类似于高阶孤儿的裂变方式。我们证明，在它们的合并效果的影响下，高阶流氓波的瓦解元素成为基本的孤子，从而产生了不对称的光谱曲线，从而产生了红色和蓝色变速的频率成分。这些观察结果揭示了在调制不稳定性诱导的超局部生成的过程中从光纤中的连续波背景中产生大量孤子的机制。
Using the generalised nonlinear Schrödinger equation, we investigate how the effect of third-order dispersion, self-steepening, and Raman-induced-self-frequency shift have an impact on the higher-order rogue waves. We observe that individually each effect breaks apart the higher-order rogue waves reducing to their constituent fundamental parts similar to how a higher-order soliton undergoes fission. We demonstrate that under the influence of their combined effect, the disintegrated elements of higher-order rogue waves become fundamental solitons creating asymmetrical spectral profiles that generate both red and blue-shifted frequency components. These observations reveal the mechanisms that create a large number of solitons in the process of modulation instability-induced supercontinuum generation from a continuous-wave background in optical fibers.
