Rodriguez, S.R.K. (author), Abass, A. (author), Maes, B. (author), Janssen, O.T.A. (author), Vecchi, G. (author), Gómez Rivas, J. (author)We demonstrate the coupling of bright and dark surface lattice resonances (SLRs), which are collective Fano resonances in 2D plasmonic crystals. As a result of this coupling, a frequency stop gap in the dispersion relation of SLRs is observed. The different field symmetries of the low- and high-frequency SLR bands lead to pronounced differences...journal article 2011

Rodriguez, S.R.K. (author), Janssen, O.T.A. (author), Lozano, G. (author), Omari, A. (author), Hens, Z. (author), Gomez Rivas, J. (author)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...journal article 2013
