我们提出了孤子型脉冲在含有二能级共振杂质和高阶色散、自陡、受激拉曼散射和受激布里渊散射等高阶效应的光波导中传输的可能性。为了建立上述结果，我们应用Painleve奇异性结构分析，并发现方程组承认Painleve属性仅为系统中涉及的物理参数的某些值。明确示出了系统方程的Lax对。由于没有共振杂质的系统中存在孤子，因此该系统也具有显著的孤子特性。
We propose the possibility of soliton-type pulse propagation in an optical guide with two-level resonant impurities and high-order effects like: higher-order dispersion, self-steepening, stimulated Raman scattering and stimulated Brillouin scattering. To establish the above results we apply the Painleve singularity structure analysis and find that the system of equations admits the Painleve property only for certain values of the physical parameters involved in the system. The Lax pair of the system equation is explicitly shown. As the system without resonant impurities admits solitons, this system is also expected to admit the remarkable solitons property.
