光子石墨烯纳米带中的离散孤子和表面孤子

Discrete and surface solitons in photonic graphene nanoribbons

Mario I. Molina, Yuri S. Kivshar

摘要:

我们分析了光在蜂窝状光子晶格中的局域化,蜂窝状光子晶格可以被视为石墨烯纳米带的光学模拟(“扶手椅”和“扶手椅”)。我们找到了空间局域态存在的条件,并讨论了晶格拓扑结构对晶格内部及其边缘激发的离散孤子性质的影响。特别是,我们发现了一种新的类型的孤子的双稳态,所谓的几何诱导的双稳态,在一个有限的范围内的晶格。

英文摘要:

We analyze localization of light in honeycomb photonic lattices restricted in one dimension which can be regarded as an optical analog of (``armchair'' and ``zigzag'') graphene nanoribbons. We find the conditions for the existence of spatially localized states and discuss the effect of lattice topology on the properties of discrete solitons excited inside the lattice and at its edges. In particular, we discover a novel type of soliton bistability, the so-called geometry-induced bistability, in the lattices of a finite extent.
