Abstract

We report on the observation of Anderson localization of near-visible light in two-dimensional systems. Our structures consist of planar waveguides in which disorder is introduced by randomly placing pores with controlled diameter and density. We show how to design structures in which localization can be observed and describe both the realization of the materials and the actual observation of Anderson localized modes by near-field scanning microscopy.

摘要

我们报告了在二维系统中观察到近可见光的安德森局域化现象。我们的结构由平面波导组成，通过随机放置具有受控直径和密度的孔来引入无序。我们展示了如何设计可以观察到局域化的结构，并描述了材料的实现以及通过近场扫描显微镜实际观察到的安德森局域模式。
