摘　　要：以变系数五次金兹堡-朗道方程为理论模型,在考虑和忽略五阶非线性克尔效应情况下,分别得到了精确的孤子解和耗散孤子解。数值模拟结果表明,这两类孤子解脉冲在非均匀光纤中都能以光孤子的形式传输。另外,考虑五阶非线性克尔效应时,分析了有微扰时光孤子的传输稳定性和双超短光脉冲相互作用。Based on the theoretical model of fifth-order Ginzburg-Landau equation with variable coefficients, and under the conditions of with or without considering the impact of fifth-order nonlinear Kerr effect, the exact soliton solution and dissipative soliton solution are obtained respectively. The numerical simulation results show that, in the inhomogeneous optical fibers, the above two kinds of pulses with soliton solutions both can propagate in the form of optical solitons. In addition, the propagation stability of optical solitons with perturbations and the interaction between two ultra-short pulses are analyzed when the fifth-order nonlinear Kerr effect is considered.
