Approximate model for surface-plasmon generation at slit apertures.
We present a semianalytical model that quantitatively predicts the scattering of light by a single subwavelength slit in a thick metal screen. In contrast to previous theoretical works related to the transmission properties of the slit, the analysis emphasizes the generation of surface plasmons at the slit apertures. The model relies on a two-stage scattering mechanism, a purely geometric diffr...
متن کاملTheory of surface plasmon generation at nanoslit apertures.
In this Letter, we study the scattering of light by a single subwavelength slit in a metal screen. In contrast with previous theoretical works, we provide a microscopic description of the scattering process by emphasizing the generation of surface plasmons at the slit apertures. The analysis is supported by a rigorous formalism based on a normal-mode-decomposition technique and by a semianalyti...
متن کاملGeneration of surface plasmons at single subwavelength slits: from slit to ridge plasmon
Understanding how surface plasmons can be launched by single subwavelength structures is crucial for the development of surface plasmonbased devices within highly integrated photonic circuits. In this paper, we study the coupling efficiency of light to surface plasmons for single slits milled in a thin metal film by analyzing the far-field optical images recorded in the Fourier plane of a leaka...
متن کاملOptimization of plasmon excitation at structured apertures.
Surface plasmon excitation that is due to a single or a structured circular aperture in a flat metallic screen is investigated theoretically and numerically with a view to enhancing the electric field close to the metallic surface. A systematic study of the homogeneous solution of the electromagnetic scattering problem is made with cylindrical coordinates, expanding Maxwell equations on a Fouri...
متن کاملImaging slit-coupled surface plasmon polaritons using conventional optical microscopy.
We develop a technique that now enables surface plasmon polaritons (SPPs) coupled by nano-patterned slits in a metal film to be detected using conventional optical microscopy with standard objective lenses. The crux of this method is an ultra-thin polymer layer on the metal surface, whose thickness can be varied over a nanoscale range to enable controllable tuning of the SPP momentum. At an opt...
