Photonic Heterostructures for Spin-Flipped Beam Splitting

Understanding and controlling chirality are important because of its ubiquity in nature. In recent years, we have witnessed the rapid development of chiral metamaterials with exceptional light-manipulating capabilities. Here, we present a design for photonic heterostructures in chiral photonics, demonstrating that photonic heterostructures stacked from achiral metasurfaces can create distinctive chiroptical functionalities. Analyses based on …
