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.

Tunable optical topological transitions of plasmon polaritons in WTe2 van der Waals films
Light: Science & Applications, 2023 Naturally existing in-plane hyperbolic polaritons and the associated optical topological transitions, which avoid the nano-structuring to achieve hyperbolicity, can outperform their counterparts in artificial metasurfaces.

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.
