Field distribution of the Z2 topological edge state revealed by cathodoluminescence nanoscopy
Photonic topological insulators with robust boundary states can enable great applications for optical communication and quantum emission, such as unidirectional waveguide and single-mode laser. However, because of the diffraction limit of light, the physical insight of topological resonance remains...
