论文摘要
拓扑光子学利用拓扑绝缘子的物理来控制光的行为。光子模式可与材料缺陷进行健壮性，这是这种控制的一个例子。在这项工作中，我们提出了一个基于支持光子拓扑绝缘子的列液晶的软性液体平台。液晶分子的方向引入了额外的几何自由度，并结合适当设计的结构特性，导致产生拓扑受到拓扑保护的光状态。使用软构件的使用可能有可能建立可利用光和软响应介质之间相互作用的可重构系统。
Topological photonics harnesses the physics of topological insulators to control the behavior of light. Photonic modes robust against material imperfections are an example of such control. In this work, we propose a soft-matter platform based on nematic liquid crystals that supports photonic topological insulators. The orientation of liquid crystal molecules introduces an extra geometric degree of freedom which in conjunction with suitably designed structural properties, leads to the creation of topologically protected states of light. The use of soft building blocks potentially allows for reconfigurable systems that exploit the interplay between light and the soft responsive medium.
