非线性波导有限阵列中的表面模和呼吸子

Surface modes and breathers in finite arrays of nonlinear waveguides

Yu. V. Bludov, V. V. Konotop

摘要:

我们提出了完整的对称和反对称(边缘和角落)的表面模式在有限的一维和二维阵列的波导。我们基于反连续极限对模式进行了分类,研究了它们的稳定性和分叉,并讨论了表面模式和体模式之间的关系。我们提出了表面呼吸子的存在,这代表了两个频率模式的阵列边缘的本地化。

英文摘要:

We present the complete set of symmetric and antisymmetric (edge and corner) surface modes in finite one-- and two--dimensional arrays of waveguides. We provide classification of the modes based on the anti-continuum limit, study their stability and bifurcations, and discuss relation between surface and bulk modes. We put forward existence of surface breathers, which represent two-frequency modes localized about the array edges.
