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. As of today, in the visible part of the spectrum, these conditions are not satisfied for any type of surface plasmon polaritons. In this paper, we demonstrate that in the…

Aluminium-Based Plasmonic Sensors in Ultraviolet

The surface plasmon polaritons generated on an Al film covered by an Al2O3 layer in the context of their application as refractive index sensors are investigated with an emphasis on amplitude-based refraction index sensing.

Long-range plasmons and epsilon-near-zero modes in ultraviolet

We theoretically investigate the propagation of surface plasmon polaritons excited by UV light in a thin layer of aluminum. It is shown that for a sufficiently thin metal layer and appropriate

Highly Confined Surface Plasmon Polaritons from Graphene Quantum Cherenkov Effect

Highly confined surface plasmon polaritons (HC-SPPs) can significantly enhance light-matter interaction and dramatically shrink electronic or photonic systems, including x-ray sources. However, due

Improving propagation lengths of ultraviolet surface plasmon polaritons on thin aluminium films by ion milling

Copper plasmonics with excitons

We investigate the propagation of surface plasmons (SPPs) in a thin layer of copper surrounded by copper oxide Cu 2 O. It is shown that particularly strong excitons in Cu 2 O can have considerable

Nanostructured optical waveguide with a highly confined mode

We propose a transmission line working at telecom wavelengths with cross section as small as ${\lambda}^2/39$, which is 1.6 times smaller than that of optimized silicon waveguide. The proposed line

Substrate material influence on the deep-ultraviolet surface plasmon resonance sensors using aluminum films

Aluminum-based deep-ultraviolet surface plasmon resonance (SPR) sensors have gained much interest in the last years. Multilayer Fresnel-based theoretical investigations were used here to investigate

Plasmonics beyond the diffraction limit

Recent years have seen a rapid expansion of research into nanophotonics based on surface plasmon–polaritons. These electromagnetic waves propagate along metal–dielectric interfaces and can be guided

Overcoming the challenge of growing ultrathin metallic films is of great importance for practical applications of nanoplasmonic structures. In the present work, epitaxial, ultrathin (<10 nm) films of

We consider propagation of surface plasmon polaritons (SPPs) in linear periodic chains (LPCs) of prolate and oblate metallic spheroids. We show that the SPP group velocity can be efficiently

Quantum Plasmonics

This review discusses and compares the key models and experiments used to explore how the quantum nature of electrons impacts plasmonics in the context of quantum size corrections of localized plasmons and quantum tunneling between nanoparticle dimers.

Mimicking Surface Plasmons with Structured Surfaces

It is established that electromagnetic waves in both materials are governed by an effective permittivity of the same plasma form, which allows the creation of designer surface plasmons with almost arbitrary dispersion in frequency and in space.

Aluminum for plasmonics.

This work observes that the energy of the plasmon resonance is determined by, and serves as an optical reporter of, the percentage of oxide present within the Al, and paves the way toward the use of aluminum as a low-cost plAsmonic material with properties and potential applications similar to those of the coinage metals.

Energy transport in metal nanoparticle chains via sub-radiant plasmon modes.

It is shown that excitation of any of these sub-radiant modes results in the most efficient energy transfer throughout the optical spectrum, with smaller interparticle separations resulting in the longest propagation.
