Recent advances in Mie-resonant metaphotonics

Abstract

Recently, we observe the emergence of a new field of all-dielectric resonant metaphotonics aiming at the manipulation of strong optically-induced electric and magnetic Mie-type resonances in dielectric nanostructures with high refractive index. Unique advantages of dielectric resonant nanostructures over their metallic counterparts are low dissipative losses and the enhancement of both electric and magnetic fields that provide competitive alternatives for some problems in plasmonics including optical nanoantennas, biosensors, active metasurfaces, and metadevices. This talk aims to highlight the recent advances in the physics and applications of all-dielectric Mie-resonant metaphotonics, including nonlinear effects, light-emitting metasurfaces, and applications of bound states in the continuum.
