利用分步傅里叶方法数值模拟研究了相同振幅的平行输入正反Airy光束在Kerr介质中脱落孤子的演化,并进一步研究了高阶效应对脱落孤子的影响。研究结果发现:Kerr介质中正反Airy光束由于相互作用,将产生类似于DNA结构的缠绕孤子,通过调整初始输入的振幅和间距,可以影响缠绕孤子的特性。另外发现:当存在单个高阶效应(三阶色散,拉曼,自陡)或者同时存在多个高阶效应时,缠绕孤子在时域和频域的演化会发生很大影响。研究结果可以为调控Airy光束产生的脱落孤子提供一些理论基础,也可以为Airy光束在超连续谱产生和宽带光源方面提供潜在的应用前景。

When a tail -leading Airy beam and a tail -trailing Airy beam with the same amplitude parallelly propagate in a Kerr medium, the evolution of shedding solitons was numerically investigated based on the split -step Fourier method. Moreover, the effect of high -order effects on rewinding solitons was further studied. It is demonstrated that rewinding solitons with the similar structure of DNA will be generated due to the interaction of a tail -leading Airy beam and a tail -trailing Airy beam. By adjusting the initial input amplitude and space int...
