About plasmons and plasmonics in graphene

2015 17th International Conference on Transparent Optical Networks (ICTON), 2015
A number of recent experimental and theoretical studies indicate the existence of THz plasmons in graphene. It is also suggested that the existence of such plasmons should be a generic property of ideal graphene, allowing for the generation of surface plasmons, which are the basis of modern plasmonics technologies. We have approached the problem from a

Color plasmons and trains of plasmons

Applied Optics, 2010
We show that a broadband surface plasmon can be excited in a thin metal film. A train of two plasmons can be excited at conditions near the condition of broadband surface plasmon excitation. Also, a method for independent multichannel checks of biochips by wavelength addressing is proposed.

Plasmon-Plasmon Interactions

Physical Review Letters, 1978
It is shown that cancellations in a consistent calculation strongly reduce the attractive interaction of plasmons in an electron gas and eliminate the possibility of a bound state of two plasmons in a metal. In degenerate semiconductors with a large static dielectric constant, a residual binding of two plasmons many remain.

A Poincaré's approach for plasmonics: the plasmon localization

Journal of Microscopy, 2008
SummaryA Poincaré's approach is employed to characterize the excitation of a plasmon, which in essence corresponds to a zero of a complex S‐matrix. Throughout this work we study the plasmonic behaviour of gold, as this metal not only is frequently used in experimental arrays, but also requires an accurate dispersion model to properly excite plasmons ...

Focusing Surface Plasmons with a Plasmonic Lens

Nano Letters, 2005
We report the focusing of surface plasmon polaritons by circular and elliptical structures milled into optically thick metallic films or plasmonic lenses. Both theoretical and experimental data for the electromagnetic nearfield is presented. The nearfield is mapped experimentally using nearfield scanning optical microscopy and plasmonic lithography. We

The Promise of PLASMONICS

Scientific American sp, 2007
Light is a wonderful medium for carrying information. Optical fibers now span the globe, guiding light signals that convey voluminous streams of voice communications and vast amounts of data. This gargantuan capacity has led some researchers to prophesy that photonic devices--which channel and manipulate visible light and other ...

Quantum Plasmonics

Proceedings of the IEEE, 2016
Quantum plasmonics is an exciting subbranch of nanoplasmonics where the laws of quantum theory are used to describe light–matter interactions on the nanoscale. Plasmonic materials allow extreme subdiffraction confinement of (quantum or classical) light to regions so small that the quantization of both light and matter may be necessary for an accurate ...

Surface Plasmons and Plasmonics

2020
Surface plasmons (SPs) correspond to self-sustaining excitations of the electron gas of metals or semiconductors, i. e., to modulations of the density of such gas occurring at the surface of the body generating electric fields propagating along the surface and decaying exponentially perpendicular to it.
