Fig. 1 (a) illustrates the simplest geometry is shown for which SPP may exist. Hot carriers (HC) generated by surface plasmon polaritons (SPPs) in noble metals are promising for application in optoelectronics, plasmonics and renewable energy. However, existing models fail to explain key quantitative details of SPP-to-HC conversion experiments. We experimentally demonstrate propagation of surface plasmon polaritons in the near-IR window lambda (1.45 microm,1.59 microm) at the interface of indium-tin-oxide films with different thicknesses deposited on glass. Dispersion of such polaritons is strongly dependent on the film thickness, putting … Surface plasmon polaritons and localized surface plasmons are discussed in the context of photonic applications.

Excitations of surface plasmon polaritons in double layer

2 Surface plasmons (SPs or surface plasmon polaritons: SPPs) are known as non-radiative optical modes due to plasma oscillations of free electrons resonantly excited at a metal surface and propagate along the surface with evanescent electromagnetic fields. For the case of metals, a major role in this process is played by surface plasmon polaritons (SPPs) propagating at the interface of the metal with the medium of incidence. Yet, simple and advanced models based on SPP propagation sometimes fail to explain experimental results, even of basic features such as the LIPSS period. Surface plasmons (SPs) are the collective oscillations of free electrons that are confined evanescently on a metal surface.

Transition metal dichalcogenide (TMD) monolayers with a direct Unidirectional surface plasmon polaritons (SPPs) at the interface between a gyrotropic medium and a simple medium are studied in a newly recognized frequency regime wherein the SPPs form narrow, beam-like patterns due to quasi-hyperbolic dispersion. The SPP beams are steerable by controlling parameters such as the cyclotron frequency (external magnetic bias) or the frequency of operation.

Design and Simulation of Nano-plasmonic Filter based on

Surface plasmon polaritons are commonly believed to be a future basis for the next generation of optoelectronic and all-optical devices. To achieve this, it is critical that the surface plasmon polariton modes be strongly confined to the surface and have a sufficiently long propagation length and a nanosize wavelength.

We report remarkably enhanced thermal emission of a hybrid structure made of a Si O 2 nanoribbon decorated with Au nanoparticles by a factor of 4 over that of a bare Si O 2 nanoribbon. The nature of surface plasmon-polaritons (SPPs) [1] is strongly dependent on the morphology of the interface on which they propagate [2]. Perhaps most dramatically the formation of Access to surface plasmon polaritons (SPPs) with directional control excited by electrical means is important for applications in (on-chip) nano-optoelectronic devices and to circumvent limitations inherent to approaches where SPPs are excited by optical means (e.g., diffraction limit).

Images of chiral SPPs on individual nanowires obtained from quantum dot fluorescence excited by the SPP evanescent field reveal the chirality predicted in our theoretical model.
