We show how the presence of nanoparticles strongly affects the propagation of surface plasmon-polaritons. In resonance, part of their energy is scattered in a privileged direction. This new result is compared to recent theoretical calculations. Moreover, hemispherical elastic surface plasmon-polariton scattering will be shown, and specific features ...

Interaction Between the Magnetic Polariton and Surface Plasmon Polariton
Volume 8C: Heat Transfer and Thermal Engineering, 2013This work numerically investigated the interaction between two resonances: the magnetic polariton (MP) and surface plasmon polariton (SPP). A reflectance contour plot of deep silver slit arrays quantitatively identified the MP mode and the SPP excitation’s dependence on the period.

Low-Threshold Surface-Plasmon-Polariton Laser Pumped by Surface Plasmon Polaritons
Conference on Lasers and Electro-Optics, 2017We demonstrate a narrow-linewidth, low-threshold surface-plasmon-polariton (SPP) laser based on a low-loss open cavity resonator leveraging grating-coupled SPPs to pump the lasing SPPs with strong spatial overlap and minimum perturbation.

Raman imaging with plasmon surface polaritons
Thin Solid Films, 1993Abstract We report on plasmon surface polariton (PSP) field-enhanced Raman spectroscopy with a two-dimensional detection system that allows microscopic imaging of ultrathin films. The technique offers a means to distinguish between coatings which are optically almost identical films but which have different Raman scattering characteristics.

Modeling of a Surface Plasmon Polariton Interferometer
MRS Proceedings, 2003ABSTRACTWe model the operation of a micro-optical interferometer for surface plasmon polaritons (SPPs) that comprises an SPP beam-splitter formed by equivalent scatterers lined up and equally spaced. The numerical calculations are carried out by using a vector dipolar model for multiple SPP scattering.

Confinement of Surface Plasmon Polaritons by Heterostructures of Plasmonic Crystals
Nano Letters, 2015Square lattice plasmonic crystals (SQ-PlCs) composed of silver pillars generate large bandgaps for surface plasmon polaritons (SPPs). SPP confinement is demonstrated using one- and two-dimensional heterostructures of SQ-PlCs comprised of cylindrical pillars with different diameters in a common square lattice.

Gap surface plasmon polaritons enhanced by a plasmonic lens
Optics Letters, 2011We numerically investigate the optical field enhancement based on gap surface plasmon polaritons (GSPPs) that are enhanced by propagating surface waves launched by a circular slit at a metal-dielectric interface. The optical field enhancement originates not only from multiple scattering and coupling of GSPPs in the spacer region between two metal ...

Photonic surfaces for surface-plasmon polaritons
Journal of the Optical Society of America A, 1997We examine the propagation of surface-plasmon polaritons on textured surfaces. Specifically, we look at how a grating surface produces a band gap in the propagation of this mode and how the band gap depends on the propagation direction of the mode. This naturally leads to a discussion of a surface profile suitable for blocking surface mode propagation ...

Introduction to Surface Plasmon-Polariton Waveguides
2010This chapter summarizes basic properties of the main Surface plasmon polariton (SPP) modes. SPPs are electromagnetic (EM) excitations that, being coupled to surface collective oscillations of free electrons in a metal, are bound to and propagate along metal-dielectric interfaces.
