Surface plasmon polariton scattering by finite-size nanoparticles

The electromagnetic Green’s tensor approach GTA is used to obtain the differential and total scattering cross sections of a finite-size nanoparticle located at a metal surface and illuminated with surface plasmon polaritons SPPs . The scattering process comprehends either elastic scattering of the incident SPP into other SPPs propagating in different directions or scattering into field componen...

Direct observation of surface plasmon-polariton dispersion.

We describe a method to observe the directional emission of electromagnetic radiation produced by the radiative decay of surface plasmonpolaritons (SPPs) that allows the dispersion of the modes in k-space to be directly visualized. The method presented here opens up the possibility of characterizing the effect of a wide range of surface morphologies on SPP dispersion. As an example we show the ...

Removal of surface plasmon polariton eigenmodes degeneracy

The effect of the tilt angle of metal film on the transmissivity of subwavelength holes in optically thick metal film is investigated. The transmission efficiency is found can be highly dependent on the tilt angle. It is also found that when the input photons are polarized not along the eigenmode directions of surface plasmon polariton, a birefringent phenomenon is observed when the array with ...

Semiconductor surface plasmon sources.

Surface-plasmon polaritons (SPPs) are propagating electromagnetic modes bound at a metal-dielectric interface. We report on electrical generation of SPPs by reproducing the analogue in the near field of the slit-doublet experiment, in a device which includes all the building blocks required for a fully integrated plasmonic active source: an electrical generator of SPPs, a coupler, and a passive...
