Measuring the characteristics of radiation scattered by surface plasmon polariton waves and detecting them in the far field is the only efficient method for studying the directivity of propagation, wave vector magnitude, and propagation length of such waves. In the present work, we demonstrate that it is possible to control the properties of surface plasmon polaritons propagating along the surface of metal nanofilms by scattering from nanoobjects, namely, nanogrooves and nanopits, formed in the nanofilms. It is shown that this technique allows the main parameters of surface plasmon polaritons to be measured.

Plasmonic nanostructures typically exhibit shifts in their resonant wavelength in response to changes in the refractive index of the surrounding medium. This limits their applications in scenarios requiring stable optical resonances. Here we present a metallic-dielectric hybrid metasurface that exhibits stable multi-wavelength resonance even if the refractive index of its surrounding varies. To quantitatively evaluate the stability of ...

We have proposed, implemented and investigated a novel, efficient quantum emitter based on an atomic-sized Ag nanocluster in a plasmonic resonator. The quantum emitter enables the realization of: (1) ultra-bright fluorescence, (2) narrow-band emission down to 4 nm, (3) ultra-short fluorescence lifetime. The fluorescence cross-section of a quantum emitter is on the order of σ ∼ 10−14 cm2, ...

We propose and realize a single-mode surface plasmon polariton (SPP) waveguide formed by two parallel grooves on the surface of a high-quality silver film. In the waveguide the SPP wave undergoes Goos–Hänchen shift of up to 0.77 of the SPP wavelength at each successive reflection, with the electric field of the SPP wave outside the ...

The effect of spherical SiO2 nanoparticles (NPs) embedded in the electrode layer of PEDOT:PSS on the efficiency of organic solar cells (OSC) based on small molecules was studied in detail. We show that embedding SiO2 NPs of 50 nm in diameter increases the power conversion efficiency (PCE) by 15%, and this increase weakly depends on ...

Because of strong light absorption by metals, it is believed that plasmonic nanostructures cannot be used for generating intensive radiation harmonics in the ultraviolet (UV) spectral range. This work presents results of investigation of nonlinear optical interaction with a single gold nanostructure, the split-hole resonator (SHR) under the state-of-the-art experimentally realized conditions. To realize interaction ...

An analytical study of the second harmonic generation by metal core - dielectric shell spherical nanoparticles was performed. Dependences of the second harmonic intensity on the dielectric shell thickness were calculated. We demonstrated that the thin coating allows tuning surface plasmon resonance wavelength, whereas in presence of the thick shell spatial Mie resonances occur. Estimated ...

We study second-harmonic generation from gold nanoislands covered with amorphous titanium oxide
(TiO2) films. As the TiO2 thickness increases, the plasmon resonance of the nanoislands shifts away from the second-harmonic wavelength of 532 nm, diminishing the resonant enhancement of the process at this wavelength. Nevertheless, the second-harmonic signal is enhanced by up to a factor of ...

Landau damping in the metal nanosphere is considered beyond the quasi-static approximation with the use of exact Mie theory when an incident plane wave can excite not only the dipole mode but also higher order modes. In resonance approximation, when one considers excitation of a single-mode, the analytical formula for the Landau damping coefficient for ...

We demonstrate effective, up to 30%, reflection of the surface plasmon-polariton wave (SPP) from a nanogroove made on Ag film surface. The use of SPP reflection from a nanogroove having a shape of parabola helps to realize a new element in nanoplasmonics—parabolic SPP mirror. It was found that the mirror allows focusing of the SPP ...

Due to losses in metals, the propagation length of the surface plasmon-polariton (SPP) waves on metal surfaces is
small. This severely limits development of numerous applications of the SPP optics: in the near-infrared spectral region propagation length of SPP waves is no longer than 200 μm as for plane SPP waves and for all types of ...

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 ...

The operation of a surface plasmon amplification by stimulated emission of radiation- (spaser)-based nanolaser is theoretically investigated. We find that the lasing frequency undergoes a shift as the lasing intensity increases, a result that agrees with recent experiments. We show that the mechanism of the intensity-dependent shift involves a spatial deformation of the lasing mode, ...
