摘　　要：以变系数高阶非线性薛定谔方程为理论模型,对光脉冲在具有五阶非线性克尔效应光纤放大器中的传输特性进行了研究。在加入振幅微扰、相位扰动、噪声微扰的情况下,数值模拟了亮孤波、灰孤波和黑孤波在光纤系统中的传输稳定性,并且讨论了孤子间的相互作用。数值模拟结果表明:在有限的微扰下,三种光脉冲具有良好的传输稳定性。The transmission characters of the solitary wave in fiber amplifier with the fifth-order non-Kerr effect were studied via using the higher-order nonlinear Schrǒdinger equation with variable coefficients. The propagation stabilities of bright-, dark-and gray-solitary wave were numerical simulated while considered the perturbation of amplitude, phase and noise, and the situation with the interaction between several solitary waves was also discussed. The simulation results showed that the three kinds of optical pulses could be transmitted stably under the weak perturbation.
