“…Hence the name "Sub-Diffraction Chains" (SDC). SDCs are potential candidates for dense integration of optical systems, and were proposed as guiding structures, junctions, and couplers [1]- [5]. Very recently, a spiral SDC was suggested as a chiral waveguide [6].…”

When a linear chain of plasmonic nano-particles is subject to longitudinal magnetic field, it exhibits optical Faraday rotation. If the magnetized nano-particles are plasmonic ellipsoids arranged as a spiral chain, the interplay between the Faraday rotation and the geometrical spiral rotation (structural chirality) can strongly enhance non-reciprocity. This interplay forms a waveguide that permits one way propagation only, within four disjoint frequency bands; two bands for each direction.

“…In Ref. 32, coupling of the surface modes of a dielectric slab and a plasmonic chain were considered from the theoretical point of view (here, one important consideration is the momentum conservation law, which can allow or forbid coupling of different modes depending on the respective dispersion relations). Generally, it can be concluded from these works that substrates play a detrimental role by suppressing propagation of SPPs or coupling them to other surface modes, which can be an unintended effect.…”

“…Thus, we do not utilize the theoretical arguments such as those employed in Ref. 32, although such considerations can be very illuminating. Our goal here is simply to investigate the transmission properties of various chains, which is achievable numerically.…”

International audienceWe have studied numerically the propagation of surface plasmon polaritons (SPPs) in linear periodic chains of plasmonic nanoparticles of different shapes. The chains are deposited on top of a thick dielectric substrate. While in many commonly considered cases the substrate tends to suppress the SPP propagation, we have found that this adverse effect is practically absent in the case when the nanoparticles have the shape of oblate spheroids with sufficiently small aspect ratio (e.g., nanodisks) whose axis of symmetry coincides with the axis of the chain

“…For small enough array-substrate spacings, not only the radiative but also the nonradiative decay properties will be altered. 26 It has been shown that under some conditions, SPP modes on the interface of the substrate can be excited and guided along the array. 27 In this paper, we modify the local environment of an array of MNPs by positioning the array close to a (partially) reflective substrate.…”

For technical reasons the number of authors shown on this cover page is limited to 10 maximum. We study theoretically the efficiency of the transmission of optical signals through a linear chain consisting of identical and equidistantly spaced silver metal nanoparticles. Two situations are compared: the transmission efficiency through an isolated chain and through a chain in close proximity of a reflecting substrate. The Ohmic and radiative losses in each nanoparticle strongly affect the transmission efficiency of an isolated chain and suppress it to large extent. It is shown that the presence of a reflecting interface may enhance the guiding properties of the array. The reason for this is the energy exchange between the surface plasmon polaritons (SPPs) of the array and the substrate. We focus on the dependence of the transmission efficiency on the frequency and polarization of the incoming light, as well as on the influence of the array-interface spacing. Sometimes the effect of these parameters turns out to be counterintuitive, reflecting a complicated interplay of several transmission channels.
