This paper recovers stationary optical soliton solutions when chromatic dispersion, in addition to self–phase modulation, is rendered to be nonlinear. The extended trial function algorithm recovers stationary soliton solutions for eleven forms of nonlinear refractive index structures of optical fibers. The technical criteria for the existence of such stationary solitons are also presented.

非线性色散和广义时间演化的平稳光学孤子的扩展试验函数方法

当除自相位调制之外的色散被设为非线性时，本文将恢复固定的光学孤子解。扩展试验函数算法为光纤的11种形式的非线性折射率结构恢复平稳孤子解。还介绍了此类固定孤子存在的技术标准。
