我们报告的安德森本地化的二维光波导阵列波导分离的无序引入沿着一个轴的阵列,在一个不相关的方式为每个波导行。我们发现,这种无序的各向异性性质引起了强烈的本地化沿着两个阵列轴。在横轴上的局部化程度仍然弱于在引入无序的方向上的程度。这种效应在理论和实验上都得到了证实。
We report Anderson localization in two-dimensional optical waveguide arrays with disorder in waveguide separation introduced along one axis of the array, in an uncorrelated fashion for each waveguide row. We show that the anisotropic nature of such disorder induces a strong localization along both array axes. The degree of localization in the cross-axis remains weaker than that in the direction in which disorder is introduced. This effect is illustrated both theoretically and experimentally.
