All-Dielectric Resonant Meta-Optics Lightens up

All-dielectric resonant nanophotonics is a rapidly developing research field driven by its exceptional applications for creating low-loss nanoscale metadevices. The tight confinement of the local electromagnetic fields and multiple interferences available in resonant photonic nanostructures can boost many optical effects and offer novel opportunities for the subwavelength control of light matter interactions. Active, light-emitting nanoscale structures are of high particular interest, as they offer unique opportunities for novel types of light sources and nanolasers. Here, we review the latest advances in this recently emerged and rapidly developing field of light-emitting dielectric resonant nanophotonics enabled by dipolar and multipolar Mietype resonances. More specifically, we discuss how to employ resonant dielectric nanostructures for the efficient control of emission from quantum dots, two-dimensional transition metal dichalcogenides, and halide perovskites. We also foresee various future research directions and applications of light-emitting all-dielectric resonant nanophotonics including but not limited to lasing in topologically robust systems, light matter interaction beyond the electric-dipole limit, and tunable light-emitting surfaces and metadevices.
