论文摘要
纯孤子是通过利用非线性傅里叶变换（NFT）在纤维激光器中首次从谐振连续波（CW）背景中提取的。可以确定的是，在非线性频域中，孤子和谐振CW背景具有不同的特征值分布。与水蒸馏相似，我们提出了孤子蒸馏的方法，通过使NFT从纤维激光器产生的稳定脉冲上进行，然后过滤出非线性频域中共振CW背景的特征值，最后通过反NFT（INFT）恢复Soliton。仿真结果验证了孤子可以与非线性频域中的共振CW背景区分开，而纯孤子可以通过INFT获得。
Pure solitons are for the first time distilled from the resonant continuous wave (CW) background in a fiber laser by utilizing nonlinear Fourier transform (NFT). It is identified that the soliton and the resonant CW background have different eigenvalue distributions in the nonlinear frequency domain. Similar to water distillation, we propose the approach of soliton distillation, by making NFT on a steady pulse generated from a fiber laser, then filtering out the eigenvalues of the resonant CW background in the nonlinear frequency domain, and finally recovering the soliton by inverse NFT (INFT). Simulation results verify that the soliton can be distinguished from the resonant CW background in the nonlinear frequency domain and pure solitons can be obtained by INFT.
