All-dielectric resonant metaphotonics: opinion

Abstract

Nanophotonics underpins the future technologies for creating reconfigurable optical circuitry for high-performing optical devices, ultrafast computers, and very compact efficient biosensors integrated on optics-driven chips with densely packed components. To localize light on the subwavelength scales, plasmonics was suggested as the only available platform. However, the recently emerged field of Mie resonant metaphotonics (or Mie-tronics ) provides novel opportunities for subwavelength optics employing resonances in high-index dielectric nanoparticles and structured surfaces. Here we present our view on this rapidly developing area of research and discuss recent advances and future trends in a design of all-dielectric structures with high quality factor ( Q factor) resonances for efficient spatial and temporal control of light.
