Topological Chiral Edge States in Deep‐Subwavelength Valley Photonic Metamaterials (Laser Photonics Rev. 16(11)/2022)

Topological Valley Photonics In article number 2200194, Rui Xi, Qiaolu Chen, Hongsheng Chen, Yihao Yang, and colleagues propose and experimentally realize topological chiral edge states in deep-subwavelength valley photonic metamaterials, which enable the miniaturization of topological photonics devices and extremely-confined self-guiding chiral edge states. The smooth transition through sharp corners demonstrate the robustness of the photonic chiral edge states.
