Metaphotonics and Metasurfaces Empowered by Mie Resonances

Abstract: Metamaterials were initially suggested for the realization of negative-index media, and later they became a paradigm for engineering electromagnetic space and control­ling propagation of waves. However, applications of metamaterials in optics are limited due to inherent losses in metals employed for the realization of artificial optical magnetism. 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 will highlight some recent advances in all-dielectric Mie-resonant metaphotonics including active and nonlinear nanophotonics as well as the recently emerged fields of topological photonics.
