Dallapiccola, RamonaGopinath, AshwinStellacci, FrancescoDal Negro, Luca2011-06-062011-06-062011-06-06200810.1364/OE.16.005544https://infoscience.epfl.ch/handle/20.500.14299/68426n this paper we investigate for the first time the near-field optical behavior of two-dimensional Fibonacci plasmonic lattices fabricated by electron-beam lithography on transparent quartz substrates. In particular, by performing near-field optical microscopy measurements and three dimensional Finite Difference Time Domain simulations we demonstrate that near-field coupling of nanoparticle dimers in Fibonacci arrays results in a quasi-periodic lattice of localized nanoparticle plasmons. The possibility to accurately predict the spatial distribution of enhanced localized plasmon modes in quasi-periodic Fibonacci arrays can have a significant impact for the design and fabrication of novel nano-plasmonics devices.WAVE-GUIDESLOCALIZATIONSPECTRUMDIFFRACTIONABSORPTIONCRYSTALSOPTICSLIGHTCHAINtext::journal::journal article::research article
