Abstract

A process for fabricating a large-area hybrid metallic nanostructure array is presented. The structures consist of an array of metal capped dielectric nanopillars and an array of metallic holes, each possessing its individual optical properties. The plasmon response of such structures can be viewed as the collection of plasmons from two geometries to form an interacting system. Experimental results show two peak values in the extinction spectrum for p-polarized incident light. The two peaks in the extinction spectrum were shifted to longer wavelength and shorter wavelength respectively with the addition of absolute ethanol on the structure surface. The narrowest extinction peak appears at normal incidence.
