Abstract

We numerically demonstrate that a periodic array of metallic nanorods sustains a maximum near-field enhancement and a far field (FF)-induced transparency at the same energy and in-plane momentum. The coupling of bright and dark plasmonic lattice resonances, and electromagnetic retardation along the nanorod length, are responsible for this effect. A standing wave with a quadrupolar field distribution is formed, giving rise to a collective suppression of FF scattering and simultaneously enhanced local fields.

Zeroth-order (a) transmittance T0, (b) reflectance R0, and (c) cut-of (a) and (b) at k=0.1rad/μm. (d) 1R0T0, (e) average NFIE at a plane intersecting the nanorods at their mid-height, and (f) cut-of (d) and (e) as solid red line at k=0.1rad/μm. In (a), (b), (d), and (e), k=0.1rad/μm is indicated by the vertical dashed lines; the solid and dash–dot lines indicate the (+1,0) and (1,0) RAs. The nanorods have dimensions 250nm×110nm×40nm. Animations of the real, y-component of the electric field in the plane of the array are shown in Media 1 and Media 2 for the high- and low-energy extinction peaks in (c). Media 3 holds for the FF-induced transparency between these peaks, which is also at the peak in (f).

(a) Zeroth-order transmittance T0 and (b) NFIE at a plane intersecting the nanorods at their mid-height. Arrays of nanorods with width=110nm, height=40nm, and variable length, are illuminated by a plane wave with k=0.08rad/μm. The labels near the SLRs indicate the associated diffraction order.

(a) Field enhancement (in color scale) and real part of the scattered field at an arbitrary phase (arrows) and (b) phase difference between the scattered and incident field in units of π. Both (a) and (b) are calculated at a plane intersecting the nanorods (delimited by the yellow lines) at their mid-height. The incident photon energy and in-plane wave vector correspond to the NF resonance at the FF-induced transparency.
