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-...

Tunneling Plasmonics in Bilayer Graphene.

We report experimental signatures of plasmonic effects due to electron tunneling between adjacent graphene layers. At subnanometer separation, such layers can form either a strongly coupled bilayer graphene with a Bernal stacking or a weakly coupled double-layer graphene with a random stacking order. Effects due to interlayer tunneling dominate in the former case but are negligible in the latte...

Towards Infrared Plasmonics in Graphene

Graphene plasmons have recently been proposed as an alternative to noble-metal plasmons in the field of photonics, due to its extremely tight light confinement, relatively long-lived collective oscillation, and high tunability via electrostatic gating. Successful support and tuning of graphene plasmonic modes rely on controllable doping of graphene to high carrier densities in nanometer-scale s...

Transformation optics using graphene.

Metamaterials and transformation optics play substantial roles in various branches of optical science and engineering by providing schemes to tailor electromagnetic fields into desired spatial patterns. We report a theoretical study showing that by designing and manipulating spatially inhomogeneous, nonuniform conductivity patterns across a flake of graphene, one can have this material as a one...

Plasmonics in graphene at infrared frequencies

We point out that plasmons in doped graphene simultaneously enable low losses and significant wave localization for frequencies below that of the optical phonon branch Oph 0.2 eV. Large plasmon losses occur in the interband regime via excitation of electron-hole pairs , which can be pushed toward higher frequencies for higher-doping values. For sufficiently large dopings, there is a bandwidth o...
