为了描述具有四阶色散、三次五次非线性、自陡峭和自频移的高速、长距离光纤传输系统中超短脉冲的传播，研究了高阶广义非线性薛定谔方程。我们得到了流氓波解决方案。研究了调制不稳定性对光杂乱波的影响：调制不稳定性增长率的增加使得光杂乱波的存在时间变短。我们通过调制不稳定性数值推导了混沌波场中的光学呼吸器。光学混沌波场的频谱可以用来指示光学呼吸器在混沌波场中的出现。混沌波场中的光流氓波也是通过调制不稳定性得到的。
For describing the propagation of ultrashort pulses in a high-speed, long-distance optical fiber transmission system with the fourth-order dispersion, cubic–quintic nonlinearity, self-steepening and self-frequency shift, a higher-order generalized nonlinear Schrödinger equation is investigated. We get the rogue-wave solutions. Effects of the modulation instability on the optical rogue waves are studied: Increasing the growth rate of the modulation instability makes the existence time of the optical rogue wave shorter. We numerically derive the optical breathers in the chaotic wave fields via the modulation instability. Spectrum of the optical chaotic wave field can be used to indicate the appearance of the optical breather in the chaotic wave field. Optical rogue waves in the chaotic wave fields are also gotten via the modulation instability.
