Abstract
Unification of different materials in a single nanophotonic system expands the frontiers of its functionalities providing wide field for optical properties engineering. Interaction of light with such nanostructures demonstrates interesting optical effects making them very attractive for different areas of science from quantum optics to biophotonics and chemistry. Therefore, design of such systems opens the door to the world of unique optical effects and non- standard applications. The resonant structures made of plasmonic metals or high-refractive index (dielectric) materials are currently considered to be the building blocks of nanophotonics. In turn, hybrid nanophotonics unifying metal and dielectric materials in a single system moves beyond basic plasmonics and all-dielectric concepts. In this talk the fabrication approaches and investigation results of such metal-dielectric nanosystems are represented. We start from nanophotonic systems composing of the mixture of metal and dielectric materials. Then the more complicated geometries are considered like nanocavities, hybrid nanosponges and asymmetrical nanosystems utilizing interference of resonances inherent to the nanostructure components. The potential of hybrid nanostructures for the applications in optically reconfigurable devices, nanoscale light sources, security labels and biosensors is also discussed.
