Abstract

We introduce the recently emerged field of all-dielectric resonant metaphotonics aiming at the manipulation of strong optically-induced electric and magnetic Mie-type resonances in dielectric and semiconductor nanostructures with relatively 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 plasmonic structures including optical nanoantennas, efficient biosensors, passive and active metasurfaces, and functional metadevices. This talk will summarize the recent advances in nonlinear, topological, and active metaphotonics. In particular, we demonstrate nanophotonic topological cavities hosting semiconductor quantum wells, and observe room-temperature lasing with narrow spectrum, high coherence, and threshold behavior. We also discuss the recent progress with optical bound states in the continuum.
