二维光子晶格中相位滑移局域模的观测
Observation of localized modes at phase slips in two-dimensional photonic lattices
摘要：
我们在实验上研究了光在二维正方形光子晶格中的相位滑移波导和相位滑移交叉点的局域化。这样的系统可以观察到各种各样的效果，包括存在的空间本地化模式的低功率，强烈的本地化状态的离散体和表面孤子的形式的生成，以及一维（1D）和2D本地化之间的交叉。
英文摘要：
We study experimentally light localization at phase-slip waveguides and at the intersection of phase-slips in a two-dimensional (2D) square photonic lattice. Such system allows to observe a variety of effects, including the existence of spatially localized modes for low powers, the generation of strongly localized states in the form of discrete bulk and surface solitons, as well as a crossover between one-dimensional (1D) and 2D localization.
