Experimental results are modeled using a finite-difference time-domain approach with the dielectric function of gold approximated by a Drude-Lorentz formula, showing a rather good agreement between the experimental and theoretical reflection and TPL enhancement spectra. The modeling is also used to optimize the array parameters for achieving strong and well-pronounced TPL enhancement maxima in the wavelength range accessible to the used experimental techniques, i.e., close to 800 nm. Accordingly designed samples are fabricated and characterized, corroborating the modeling predictions. We discuss the origin of TPL enhancement and its relation to local-field enhancements at the sample surface as well as its characterization with TPL microscopy. The implications of the obtained results are also discussed.The authors acknowledge support from the European Network of Excellence, Plasmo-Nano-Devices (FP6-2002-IST- 1-507879 , the STREP “Surface Plasmon Photonics” FP6- NMP4-CT-2003-505699) the NABIIT project (Contact No. 2106-05-033 from the Danish Research Agency) and the Spanish Ministry of Education and Science (Grant No. MAT2005-06608-C02).Peer reviewedAmerican Physical Society200920092007info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501259768 bytesapplication/pdfhttp://hdl.handle.net/10261/19378reponame:DIGITAL.CSIC.
