Control of light at the nanoscale is demanding for future successful on-chip integration. At the subwavelength scale, the conventional optical elements such as lenses become not functional, and they require conceptually new approach for a design of nanoscale photonic devices. The most common approach to the subwavelength photonics is based on plasmonic nanoparticles and plasmonic waveguides due to their ability to capture and concentrate visible light at subwavelength dimensions. But the main drawback of all plasmonic devices is their intrinsic losses due to metallic components which affect strongly the overall performance of plasmonic structures limiting their scalability and practical use.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
