We study the influence of third-order dispersion effects on the propagation of an incoherent nonlinear wave in an optical fiber system. The wave spectrum is shown to exhibit a highly asymmetric deformation characterized by a lateral spectral shoulder and the subsequent formation of an unexpected constant spectral pedestal. A kinetic approach to the problem reveals the existence of an invariant that explains in detail the essential properties of such asymmetric spectral evolution of the wave.
我们研究了三阶色散效应对光纤系统中非相干非线性波传播的影响。结果表明，波谱表现出高度不对称的变形，其特征为横向谱肩和随后形成的意想不到的恒定谱底座。对该问题的动力学方法揭示了不变量的存在，该不变量详细解释了波的这种不对称谱演化的基本性质。
