以高阶复系数Ginzburg-Landau方程为模型,就高阶非线性效应(比如:三阶色散、自陡峭、自频移等)对呼吸孤子传输特性的影响进行了详细的分析,结果表明:当各高阶非线性效应单独作用时,可能会导致呼吸孤子形状的不对称或脉冲中心偏移等现象,但是,当它们共同作用于呼吸孤子时,适当的参数选取可以使它们对呼吸孤子的影响相互抵消,从而使呼吸孤子实现保型传输。

Based on the higher-order complex Ginzburg-Landau equation, the impacts of higher-order nonlinear effects, such as the third-order dispersion, self-steepening effect and self-frequency shift effect et al, have been studied in detail. The results show that only one high-order nonlinear effect always brings the soliton profile asymmetric or the pulse center’s movement. But when they exist together, the interaction between them may balance the impact of them on the breathing solitons by choosing the parameter values reasonably.
