چکیده
Abstract The propagation of surface-plasmon-polariton (SPP) waves at the planar interface a metal and dielectric material was investigated for with strongly temperature-dependent constitutive properties. silver vanadium multioxide impregnated combination active dyes. Depending upon volume fraction multioxide, either attenuation or amplification SPP may be achieved; degree is dependent on both temperature whether increasing decreasing. At intermediate fractions fixed temperature, wave experience if but

Surface-plasmon-polariton–assisted dissipative backaction cooling and amplification
We evaluate a method, based on the near-field properties of surface-plasmon polaritons, to significantly enhance the dissipative optomechanical backaction mechanism. Although the large momentum of the surface-plasmonpolariton modes leads to the enhanced sensitivity of the scattering to the mechanical displacement, the overall efficiency will not improve unless an optical antenna efficiently cou...
متن کاملManipulating surface-plasmon-polariton launching with quasi-cylindrical waves
Launching the free-space light to the surface plasmon polaritons (SPPs) in a broad bandwidth is of importance for the future plasmonic circuits. Based on the interference of the pure SPP component, the bandwidths of the unidirectional SPP launching is difficult to be further broadened. By greatly manipulating the SPP intensities with the quasi-cylindrical waves (Quasi-CWs), an ultra-broadband u...
متن کاملEnhanced Surface Plasmon Polariton Propagation Induced by Active Dielectrics
We present numerical simulations for the propagation of surface plasmon polaritons (SPPs) in a dielectric-metal-dielectric waveguide using COMSOL multiphysics software. We show that the use of an active dielectric with gain that compensates metal absorption losses enhances substantially plasmon propagation. Furthermore, the introduction of the active material induces, for a specific gain value,...
متن کاملDirect observation of surface plasmon-polariton dispersion.
We describe a method to observe the directional emission of electromagnetic radiation produced by the radiative decay of surface plasmonpolaritons (SPPs) that allows the dispersion of the modes in k-space to be directly visualized. The method presented here opens up the possibility of characterizing the effect of a wide range of surface morphologies on SPP dispersion. As an example we show the ...
متن کاملRemoval of surface plasmon polariton eigenmodes degeneracy
The effect of the tilt angle of metal film on the transmissivity of subwavelength holes in optically thick metal film is investigated. The transmission efficiency is found can be highly dependent on the tilt angle. It is also found that when the input photons are polarized not along the eigenmode directions of surface plasmon polariton, a birefringent phenomenon is observed when the array with ...
