Apertures with diameters below the wavelength of light represent a nanoscale structure with interesting novel properties. They are usually discussed in an array setting leading to integral optical (spectroscopic) effects. We present here results obtained by a combination of such apertures (but investigated as an individual structure) with metal nanoparticles. These nanoparticles are known to exhibit surface plasmon resonance. The optical effect resulting from the combination of both structures were studied by a complementary ultra structural (AFM, SEM) and spectroscopic characterization on the single aperture level, yielding insights into this promising novel nanophotonic element.
