Few-Cycle Surface Plasmon Polaritons. [PDF]

Nano Lett
Surface plasmon polaritons (SPPs) can confine and guide light in nanometer volumes and are ideal tools for achieving electric field enhancement and the construction of nanophotonic circuitry. The realization of the highest field strengths and fastest switching requires confinement also in the temporal domain.

Surface Plasmon Polariton Graphene Photodetectors [PDF]

Nano Letters, 2015
The combination of plasmonic nanoparticles and graphene enhances the responsivity and spectral selectivity of graphene-based photodetectors. However, the small area of the metal-graphene junction, where the induced electron-hole pairs separate, limits the photoactive region to submicron length scales.

Confined Surface Plasmon–Polariton Amplifiers [PDF]

Nano Letters, 2013
We demonstrate the realization of confined surface plasmon polariton amplifiers using a thin layer of the organic gain medium 4-dicyanomethylene-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran dispersed in a tris(8-hydroxy-quinolinato)aluminum matrix. Complete loss compensation, which occurs at a pump fluence of approximately 200 μJ/cm(2), is directly ...

Theory of surface plasmons and surface-plasmon polaritons [PDF]

Reports on Progress in Physics, 2006
Collective electronic excitations at metal surfaces are well known to play a key role in a wide spectrum of science, ranging from physics and materials science to biology. Here we focus on a theoretical description of the many-body dynamical electronic response of solids, which underlines the existence of various collective electronic excitations at ...

Robust and Broadband Graphene Surface Plasmon Waveguide Coupler via Quantum Control

Frontiers in Physics, 2022
In this article, a novel graphene subwavelength waveguide coupler is designed based on the quantum control theory. Compared with metal surface plasmon polaritons (SPPs), graphene surface plasmon polaritons (GSPPs) have a smaller SPP wavelength and ...

Surface Plasmon Polaritons on Metallic Surfaces

Optics and Photonics News, 2007
A unified theoretical study of surface plasmon polaritons on flat metallic surfaces and interfaces is undertaken to clarify the nature of these electromagnetic waves, conditions under which they are launched, and the restrictions imposed by Maxwell's equations that ultimately determine the strength of the excited plasmons.

Scattering of a surface plasmon polariton by a surface defect [PDF]

Physical Review B, 1994
By means of a Green-function, volume-integral-equation approach we study numerically the scattering of a surface plasmon polariton at a planar vacuum-metal interface by dielectric and metallic defects that are either embedded in the metal substrate or are situated in the vacuum region on the substrate.

Surface plasmon polariton absorption modulator

Optics Express, 2011
An electrically controlled ultra-compact surface plasmon polariton absorption modulator (SPPAM) is proposed. The device can be as small as a few micrometers depending on the required extinction ratio and the acceptable loss. The device allows for operation far beyond 100 Gbit/s, being only limited by RC time constants.
