Coherent surface plasmon amplification through the dissipative instability of 2D direct current

open access: yesNanophotonics, 2018
We propose an original concept for on-chip excitation and amplification of surface plasmon polaritons. Our approach, named nanoresotron, utilizes the collective effect of dissipative instability of a 2D direct current flowing in vicinity of a metal ...

Two-plasmon spontaneous emission from a nonlocal epsilon-near-zero material

open access: yesCommunications Physics, 2021
Plasmonics involves the engineering of light-matter interactions and has range of possible uses in the study of quantum phenomenon, but efficient plasmonic sources are required.

Surface Plasmon Launching by Polariton Superradiance [PDF]

open access: yesACS Photonics, 2019
The condition of phase matching prohibits the transfer of excitation from free-space photons to surface plasmon polaritons (SPP). We propose and analyze a scheme that excites an ensemble of emitters in a collective state, which is phase matched with the SPP by the optical pulses used for its preparation. By a collective enhancement the ensemble, hence,

Anisotropic excitation of surface plasmon polaritons on a metal film by a scattering-type scanning near-field microscope with a non-rotationally-symmetric probe tip

open access: yesNanophotonics, 2018
We investigated the excitation of surface plasmon polaritons on gold films with the metallized probe tip of a scattering-type scanning near-field optical microscope (s-SNOM). The emission of the polaritons from the tip, illuminated by near-infrared laser

Experimental nanofocusing of surface plasmon polaritons using a gravitational field

open access: yesNanophotonics, 2020
How to capture electromagnetic fields into sub-wavelength spatial scales has been a major challenge in nanophotonics, especially confining surface plasmon polaritons into regions as small as a few nanometers.

Conversion of a Helical Surface Plasmon Polariton into a Spiral Surface Plasmon Polariton at the Outlet of a Metallic Nanohole

open access: yesACS Omega, 2022
The conversion of a helical surface plasmon polariton (SPP) creeping out of a circular nanohole in a thick metal (Ag or Au) film into a spiral (Hankel type) SPP outward propagating at the film's interface is studied theoretically. The dispersion relations of SPPs of various modes in a nanohole, calculated from a transcendental equation, show that the ...
