拓扑保护边状态的谷排序和路由
Sorting and Routing Topologically Protected Edge States by their Valleys
摘要：
我们实验证明和表征的光子平台包含异构拓扑相位。该平台被示出为支持谷自旋锁定边缘状态，该谷自旋锁定边缘状态可以基于其自旋和谷自由度被路由。通过改变嵌入自旋霍尔光子晶体内的谷光子晶体的拓扑结构来实现布线。
英文摘要：
We experimentally demonstrate and characterize a photonic platform containing heterogeneous topological phases. This platform is shown to support valley-spin locked edge states that can be routed based on their spin and valley degrees of freedom. The routing is accomplished by changing the topology of the valley photonic crystal embedded inside a spin-Hall photonic crystal.
