“…The quantity to be maximized here was the short circuit current in the 375-750-nm range, assuming a quantum yield equal to 1, as described in [13]. Among the different algorithms which were tested, differential evolution (DE) proved to be the most efficient algorithm for this kind of problem, generating solutions faster and more reliably than any other global algorithm [10].…”

“…An alternative way to obtain the fields in the layers and the measured quantities as the reflectance and transmittance is by using the scattering-matrix formalism, which has better numerical stability for evanescent waves (Whittaker and Culshaw, 1999;Defrance et al, 2016;Orfanidis, 2016). The scattering-matrix was introduced by Wheeler in the context of quantum physics (Wheeler, 1937), but has been also applied in solid state physics (Ko and Inkson, 1988), electrical engineering (Orfanidis, 2016), and optics (Whittaker and Culshaw, 1999;Yuffa and Scales, 2012;Defrance et al, 2016). The S-matrix relates the forward and backward field amplitudes in the layer l and in the layer l ′ in an entirely different way.…”

Thin films of noble metals with thickness smaller than the wavelength of light constitute one of the most investigated structures in plasmonics. The fact that surface plasmon modes can be excited in these films by different ways and the simplicity of fabrication offer ideal conditions for applications in nanophotonics. The generation of optical modes in coupled Fabry-Pérot planar cavities and their migration to hyperbolic metamaterials is investigated. Coupled Fabry-Pérot cavities behave as simple coupled resonators. When the intra-cavity media have different refractive indices in two or more coupled cavities resonance anti-crossings arise. The application of this kind of strong coupling in sensing is foreseen. Beyond the cavity modes excited by propagating waves, also long range plasmonic guided modes can be excited using emitters or evanescent waves. A periodic structure made by multiple plasmonic films and dielectrica supports bulk plasmons, of large propagation constant and increasing field amplitude. The optical response of these structures approaches that of the hyperbolic metamaterial predicted by the effective medium theory. Light can propagate with full transmission in a structure made of a photonic crystal based on quarter wavelength layers and a second photonic crystal with an overlapping forbidden band, but presenting a non-trivial topological phase achieved by band inversion. This is due to excitation of optical Tamm states at the boundary between both crystals. The extension to multiple optical Tamm states using dielectric and plasmonic materials and the symmetries of the edge states is investigated.

allow for a strong confinement and enhancement of the electromagnetic field in subwavelength volumes along with plasmon propagation in structures with low dimensionalities. [2] These appealing properties have triggered the development of biosensing, [3] energy conversion, [4,5] detectors, [6] integrated optical component for information transfer and/or processing, [7] or shaping of the phase front of light. [8,9] Several applications rely on the ability of the plasmonic nanoparticle to efficiently scatter or concentrate the light in a specific region of space at a given energy. As a consequence, a constant effort has been undertaken to control and tune the plasmon resonance of subwavelength plasmonic resonators or antennas from UV to IR. [10,11] Strategies to adjust the conditions of resonance or propagation rely on the static [12,13] or dynamic [14][15][16] modification of the surrounding medium, on the modification of the geometry, [17] the size or the material of the metallic object itself, [12,18,19] or on the modification of the charge carrier density, for instance. [20] A particularly efficient approach exploits the electromagnetic coupling between a plasmonic nanoparticle and a thin metallic film. [21][22][23][24][25][26] The small nanocavity resulting from the metalinsulator-metal (MIM) geometry gives rise to new longitudinal and transverse plasmonic resonances in the gap along with a spectral shift of the native resonance of the nanoparticle. [27][28][29] The adjustment of the coupling strength by varying the distance between nanoparticles and the conductive plasmonic film can be used to tune the surface plasmon (SP) resonance wavelength. [30][31][32] The MIM geometry, which is compatible with operational device configuration, offers therefore a new degree of freedom to control the modal plasmonic landscape and the related scattering properties of the system.While the optical response of subwavelength particles is well defined and usually limited to one or two resonances in the visible, sub-micronic 2D colloidal gold cavities sustain multiple higher order plasmonic resonances that offer a much richer multimodal plasmonic spectrum. Indeed, these highly crystalline and thin metallic cavities exhibit a single transverse mode but several planar resonances of higher order than the dipolar one in the visible and near-infrared. [33][34][35][36] They result from multiple interferences between degenerated high order SP modes and yield optical near-fields that are strongly localized at specific hot spots along the edges and at the center of the Sub-micrometric and ultrathin gold cavities sustain several high order planar plasmon resonances in the visible to near-infrared spectral window that open new perspectives for the realization of self-assembled metasurfaces or integrated components for nano-optics. This article investigates in detail the far-field spectral features of these multimodal crystalline gold nanoprisms, deposited on either dielectric (glass) or metallic substrates (Au, Al) by darkfield scattering s...
