| Popis: | Recently there have been significant interests about fabrication of optical nanopore with its diameter range of 5 nm–10 nm for single molecule analysis and manipulation. However, due to very small amount of the optical intensity through the tiny size of the nano-aperture much smaller than the optical wavelength, the optical intensity enhancement via plasmonic effect by using pore array or periodic groove patterns have been tried. Also, the double slits with nanoscale width are reported to provide the constructive periodic modulation for the transverse-magnetic (TM) wave mode. In this report, the Au aperture arrays sidelined with the nanoscale double slit, and surrounded by 4 nanoscale slits have been fabricated with optical characterization in the visible range. |
