由于孤子在光学数据传输中的应用，孤子在光子学中具有重要的基础作用，也是研究从以新频率产生光、捕获波到流氓波等新现象的工具。孤子也是运动的散射体：它们会产生以光速运动的折射率微扰。在这里，我们发现这种微扰以一种不寻常的方式散射光：它们通过正负频率的混合放大光，正如我们使用一次伯恩近似和数值模拟所描述的那样。可以观察到这些效应的最简单场景是在光孤子传播的初始阶段：形成陡峭的激波阵面，它可以有效地将第二个较弱的探测脉冲散射成相对较强的正负频率模式，并以牺牲孤子为代价。我们的结果显示了一种新的依赖于孤子诱导散射的全光放大方案。
Solitons are of fundamental importance in photonics due to applications in optical data transmission and also as a tool for investigating novel phenomena ranging from light generation at new frequencies and wave-trapping to rogue waves. Solitons are also moving scatterers: they generate refractive index perturbations moving at the speed of light. Here we found that such perturbations scatter light in an unusual way: they amplify light by the mixing of positive and negative frequencies, as we describe using a first Born approximation and numerical simulations. The simplest scenario in which these effects may be observed is within the initial stages of optical soliton propagation: a steep shock front develops that may efficiently scatter a second, weaker probe pulse into relatively intense positive and negative frequency modes with amplification at the expense of the soliton. Our results show a novel all-optical amplification scheme that relies on soliton induced scattering.
