在这项研究中，我们成功地设计了超高速光纤传输系统所需的超短孤子分子，通过在存在损耗和周期放大的情况下进行平均色散管理。我们还系统地数值研究了三阶色散、自陡化和受激拉曼散射对飞秒范围内两孤子和三孤子分子行为的单独和联合影响，特别是关于呼吸因子。结果表明，所有考虑的高阶效应都严重阻碍了孤子分子的传播。最后，我们认为，最佳的三阶色散补偿，结合呼吸因子的正确选择，可能会减少由于自陡化和受激拉曼散射而造成的惩罚。
In this study we successfully designed ultrashort soliton molecules, required for ultra-high-speed fibre transmission systems, by means of average dispersion management in the presence of losses and periodic amplification. We also conducted a systematic numerical investigation of the individual and combined impacts of third-order dispersion, self-steepening and stimulated Raman scattering on the behaviour of two- and three-soliton molecules in the femtosecond regime, in particular, with respect to the breathing factor. We show that all the considered higher-order effects substantially hinder the propagation of soliton molecules. Finally, we suggest that optimal third-order dispersion compensation, combined with a correct choice of the breathing factor, may allow reduction of the penalties due to self-steepening and stimulated Raman scattering.
