On-Chip All-Dielectric Metasurface Enables Creation of Topological

In a groundbreaking advancement in photonics, researchers from Wuhan University and Tsinghua University have pioneered a revolutionary platform that integrates topological exceptional points (EPs) within an all-dielectric, on-chip metasurface. This innovative strategy dispenses with traditional metallic components, thereby circumventing the notorious Ohmic losses associated with metal-based metasurfaces. By leveraging precise extraction methods …
