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.

Inhomogeneous Surface Plasmon Polaritons [PDF]
ACS Photonics, 2014 We show analytically and with rigorous computational electrodynamics how inhomogeneous surface plasmon polaritons (ISPPs) can be generated by refraction of ordinary SPPs at metal–metal interfaces. ISPPs, in contrast with SPPs, propagate and decay in different directions and can therefore exhibit significantly different intensity patterns.

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

Plasmonics: Localization and guiding of electromagnetic energy in metal/dielectric structures [PDF]
, 2005 We review the basic physics of surface-plasmon excitations occurring at metal/dielectric interfaces with special emphasis on the possibility of using such excitations for the localization of electromagnetic energy in one, two, and three dimensions, in a ...

Two-plasmon spontaneous emission from a nonlocal epsilon-near-zero material
Communications 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 polaritons in strained Weyl semimetals
, 2020 Surface plasmon polaritons in a strained slab of a Weyl semimetal with broken time-reversal symmetry are investigated. It is found that the strain-induced axial gauge field reduces frequencies of these collective modes for intermediate values of the wave

Nanophotonics, 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
Nanophotonics, 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.
