以描述超短光脉冲在光纤中传输的高阶非线性Ginzburg-Landau方程为模型,给出了包含三阶色散,自陡效应以及非线性延迟响应等效应的锁模激光器系统的啁啾类孤波解,并采用分步傅立叶方法对该解析解的稳定性进行了详细的分析。结果表明:在一定的系统参数条件下,即使存在一些微弱的扰动,这类啁啾类孤波解依然可以稳定地存在并传输较长的距离。如果初始输入脉冲为任意的高斯脉冲,在经过一段传输距离的演化后,啁啾类孤波解形成并可以稳定传输。 相似文献

The generalized form with varying coefficients for nonlinear Schrödinger equation including fourth-order dispersion and quintic nonlinearity is presented in this article. The exact bright, dark, and combined solitonlike solutions were given by taking proper ansatz into account. The different forms of dispersion functions were considered to investigate the pulse's evolution or dispersion managements in optical fiber. 相似文献

We report wide class of exact solutions of the modified Gross–Pitaevskii equation (GPE) in "smart" Jacobian elliptic potentials, in the presence of external source. Solitonlike solutions, singular solutions, and periodic solutions are found using a recently developed fractional transform in which all the amplitude parameters are nonzero. These results generalize those contained in (T. Paul, K. Richter and P. Schlagheck, Phys. Rev. Lett. 94 (2005) 020404.) for nonzero trapping potential. 相似文献
