Anapole-Mediated Emission Enhancement in Gallium Nitride Nanocavities
Anapole-Mediated Emission Enhancement in Gallium Nitride Nanocavities
Benefiting from their low-loss light manipulation at subwavelength scales, optically resonant dielectric nanostructures have emerged as one of the most promising nanophotonic building blocks. Here, we theoretically conceive a dielectric nanocavity made of moderate-refractive-index gallium nitride and investigate the strong electromagnetic field confinement inside the nanocavity. We demonstrate that gallium …
