Description:
Author(s): Zhen Gao, Zhaoju Yang, Fei Gao, Haoran Xue, Yahui Yang, Jianwen Dong, and Baile Zhang The valley Hall effect and topological valley edge states are two fundamental properties in gapped valleytronic materials, such as MoS 2 and biased bilayer graphene. Such properties have paved the way for applications in valleytronics. Here, the authors experimentally demonstrate a valley surface-wave photonic crystal on a single metal surface, as the photonic analog of the valley-Hall topological insulator phase. The photonic valley-Hall effect with valley-chirality locked beam splitting, and topological valley-polarized edge states, are demonstrated for the first time on a photonic platform. [Phys. Rev.
