Paper Abstract
Double nanohole apertures in metal films have proven to be efficient plasmonic devices for trapping nanoparticles as small as single proteins.1 To date, this technique has relied on weak transmission far beyond the wavelength cutoff, ignoring the prospect of plasmon field enhancement. In this work we present details on the design and fabrication of arrays of nanoring apertures on gold films. These devices feature efficient light localization in small gaps similar to double nanohole apertures, but additionally benefit from surface plasmon resonances in the near infrared spectrum. We perform polarization-resolved spectrometry on the arrays and discuss their potential for nanoparticle trapping.
