啁啾光晶格边缘表面孤子的动力学

Dynamics of surface solitons at the edge of chirped optical lattices

Yaroslav V. Kartashov, Victor A. Vysloukh, Lluis Torner

摘要:

研究了刻在克尔型非线性介质中啁啾光晶格边缘的孤子形成。我们发现家庭的功率无阈值表面波,不存在于其他类型的晶格界面。这种孤子的形成是由于界面处的内反射、分布布拉格反射和聚焦非线性的共同作用。值得注意的是,我们发现啁啾晶格的表面是孤子吸引子:在能量阈值以下,在晶格内发射的孤子自弯曲到界面,然后粘在界面上。

英文摘要:

We address soliton formation at the edge of chirped optical lattices imprinted in Kerr-type nonlinear media. We find families of power thresholdless surface waves that do not exist at other types of lattice interfaces. Such solitons form due to combined action of internal reflection at the interface, distributed Bragg-type reflection, and focusing nonlinearity. Remarkably, we discover that surfaces of chirped lattices are soliton attractors: Below an energy threshold, solitons launched well within the lattice self-bend toward the interface, and then stick to it.
