Resonant hybrid metal-dielectric nanostructures bridging the gap between plasmonics and high refractive index (dielectric) nanoparticles has become a fast-developing field of nanophotonics. Indeed, manipulation of optical resonances of metal and/or dielectric components of united hybrid nanosystem pave the way to enhance optical effects as well as demonstrate new ones, and as a result, realize wide range of applications.
In this talk we start from a description of the optical properties which can be implemented in different metal-dielectric nanostructures. Then the fabrication techniques making possible to create a large platelet of hybrid nanostructures geometries (e.g. hybrid nanosponges, asymmetrical nanoantennas, etc.) are discussed. The particular emphasis is placed to optical properties in such systems originating from both material properties and resonant behavior of the nanostructure components, e.g. optical generation of static electric field, white light luminescence spectra control by the microstructure reconfiguration, second harmonic generation tuning through unification of plasmonic, semiconductor and polymer materials in a single system, etc. The application potential of metal-dielectric nanostructures for nanoscale light sources, unclonable security labels, reconfigurable devices, biosensors bi-functional sensor-catalytic systems is also described. Finally, perspectives of hybrid nanophotonics development are also highlighted.
