Magnetic light and all-dielectric nanophotonics

We review a new, rapidly emerging field of all-dielectric nanophotonics aimed at manipulating strong optically-induced electric and magnetic resonances in high-refractive-index dielectric and semiconductor nanostructures. Unique advantages of dielectric nanostructures over metallic plasmonic structures are their low dissipative losses that provide new and competitive alternatives for nanoantennas and optical metamaterials. We will demonstrate that resonances in such dielectric nanostructures can boost performance of many photonic devices in the visible and near-IR frequency spectra
