Dielectric Resonant Metaphotonics

Recent rapid progress in subwavelength optics and nanophotonics with dielectric structures is underpinned by the physics of Mie resonances excited in nanoparticles with a high refractive index, and it suggests a novel platform for the localization of light in subwavelength photonic structures and opens new horizons for metamaterial-enabled photonics or metaphotonics. In this invited paper, we review the recent advances in Mie-resonant metaphotonics (also termed as Mie-tronics) for isolated high-index dielectric nanoparticles (or nanoantennas) and nanoparticle structures such as resonant dielectric metasurfaces, as well as their applications to topological photonics. We also oversee the future developments of this active field and its links to other research areas.
