论文摘要
局部非线性波的相互作用，例如孤子和调制不稳定性模式是非线性科学的引人入胜且深入研究的话题。在这份研究报告中，我们报告了电信光纤中一种新型的呼吸互动类型的观察，其中两个相同的呼吸器以相反的组速度传播。在某些条件下，放大和歼灭都不发生在碰撞点，最有趣的是，它的振幅几乎等于另一个振荡的呼吸器的另一个最大值。这种类似幽灵的呼吸互动动力学可以通过非线性schrödinger方程的N-呼吸道解决方案充分描述。
Mutual interaction of localized nonlinear waves, e.g. solitons and modulation instability patterns, is a fascinating and intensively-studied topic of nonlinear science. In this research report, we report on the observation of a novel type of breather interaction in telecommunication optical fibers, in which two identical breathers propagate with opposite group velocities. Under certain conditions, neither amplification nor annihilation occur at the collision point and most interestingly, its amplitude is almost equal to another maximum of either oscillating breather. This ghost-like breather interaction dynamics can be fully described by the N-breather solution of the nonlinear Schrödinger equation.
