Abstract
Recently there have been tremendous interests for developing the single molecule analysis device. We have previously reported the fabrication of the nanopores and nano-slit pores on the various nanostructures such as the Au-coated pyramid and the flat membrane for optical detection detection device. In this report, we address the fabrication of the various nano-aperture optical platform, and optical characterization of the fabricated devices. For aperture opening less than 50 nm, the strong spp-mediated intraband transmission peak at 500 nm is presented, while for the aperture size greater than 200 nm, the surface plasmonic coupling peaks among the nano-apertures are observed. As an example, we present the optical intensities measured from the various size of the nanopores on pyramid as in figure. The fabricated spp-mediated optical intensites from the optical platform device can be utilized for the next generation optical detection device. Figure 1
