Strong Geometrical Dependence of the Absorption of Light in Arrays of Semiconductor Nanowires
TL;DR: It is demonstrated experimentally that arrays of base-tapered InP nanowires on top of an InP substrate form a broad band and omnidirectional absorbing medium and the first study of the influence of the geometry of the nanowire on the enhancement of the optical absorption by arrays is presented.
Journal ArticleDOI
Coupling Bright and Dark Plasmonic Lattice Resonances
Said Rk Rodriguez,Aimi Abass,Bjorn Maes,O.T.A. Janssen,G. Vecchi,J. Gómez Rivas,J. Gómez Rivas +6 more
TL;DR: In this paper, the authors demonstrate the coupling of bright and dark surface lattice resonances (SLRs), which are collective Fano resonances in 2D plasmonic crystals.
Journal ArticleDOI

TL;DR: In this paper, a comparison among several fully-vectorial methods applied to a basic scattering problem governed by the physics of the electromagnetic interaction between subwavelength apertures in a metal film is presented.

Coupling Bright and Dark Plasmonic Lattice Resonances
Said Rk Rodriguez,Aimi Abass,Bjorn Maes,O.T.A. Janssen,G. Vecchi,J. Gómez Rivas,J. Gómez Rivas +6 more
TL;DR: In this paper, the authors demonstrate the coupling of bright and dark surface lattice resonances (SLRs), which are collective Fano resonances in 2D plasmonic crystals.
Journal ArticleDOI
On the phase of plasmons excited by slits in a metal film
TL;DR: The excitation of surface plasmons by subwavelength slits in metal films is studied using a rigorous diffraction model and it is shown that the plasmon is launched by a slit in antiphase with the incident magnetic field.
