Simple design rules are developed for the particular case of a slit-groove array with a given number of grooves that are symmetrically distributed with respect to a central slit. These rules take advantage of the hybridization of Fabry-Perot modes in the slit and surface modes of the corrugated metal surface. Same design rules apply for optical and infrared frequencies. The parameter space of the groove array is also examined with a conjugate gradient optimization algorithm that used as a seed the geometries optimized following physical intuition. Both uniform and nonuniform groove arrays are considered. The largest transmission enhancement, with respect to a uniform array, is obtained for a chirped groove profile. Such relative enhancement is a function of the wavelength. It decreases from 39 % in the optical part of the spectrum to 15 % at the long wavelength infrared. info:eu-repo/grantAgreement/ES/MINECO/MAT2011-28581-C02 info:eu-repo/grantAgreement/EC/FP7/247991/EU/PLAsmonic Innovative Sensing in the IR/PLAISIR info:eu-repo/grantAgreement/EC/FP6/034506/EU/Plasmon enhanced Photonics/PLEAS info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.546 2012 OPTICS 4 / 80 = 0.05 2012 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-2101-8862 López-Tejeira, Fernando.
