Transformation optics for plasmonics.
A new strategy to control the flow of surface plasmon polaritons at metallic surfaces is presented. It is based on the application of the concept of transformation optics to devise the optical parameters of the dielectric medium placed on top of the metal surface. We describe the general methodology for the design of transformation optical devices for surface plasmons and analyze, for proof-of-...
متن کاملTransformation Optics Approach to Plasmon-Exciton Strong Coupling in Nanocavities.
We investigate the conditions yielding plasmon-exciton strong coupling at the single emitter level in the gap between two metal nanoparticles. Inspired by transformation optics ideas, a quasianalytical approach is developed that makes possible a thorough exploration of this hybrid system incorporating the full richness of its plasmonic spectrum. This allows us to reveal that by placing the emit...
متن کاملElectrically tunable graphene plasmonic quasicrystal metasurfaces for transformation optics
The past few years have witnessed tremendous achievements of transformation optics applied to metallic plasmonic systems. Due to the poor tunability of metals, however, the ultimate control over surface plasmons remains a challenge. Here we propose a new type of graphene plasmonic (GP) metasurfaces by shaping the dielectrics underneath monolayer graphene into specific photonic crystals. The rad...
متن کاملOptical metasurfaces: from planar to conformable optics
Abrupt modifications of the fields across an interface can be engineered by depositing an array of subwavelength resonators specifically tailored to address local amplitude, phase and polarization changes [1]. Physically, ultrathin nanostructure arrays, called “metasurfaces”, control light by engineering artificial boundary conditions of Maxwell’s equations. Metasurfaces have been implemented t...
متن کاملUltra hybrid plasmonics: strong coupling of plexcitons with plasmon polaritons.
We report a ternary-coupled plasmonic system consisting of excitons of J-aggregated dye, localized surface plasmon polaritons of Ag nanoparticles, and propagating surface plasmon polaritons of continuous Ag film. J-aggregate dyes are uniformly self-assembled on colloidally synthesized Ag nanoprisms forming plexcitonic nanoparticles, which are placed at a distance nanometers away from the Ag thi...
