Abstract

We present a three-dimensional metallic nano-structure, which consists of a nano-hole array in a gold membrane and a co-registered array of gold nano-disks situated on a substrate below the membrane. This structure provided a transmission resonance due to a localized surface plasmon (LSP) interaction between each hole and co-registered disk. Both numerical and experimental results demonstrated that the position of the LSP resonance transmission depended greatly on hole and disk diameter. Enhanced electric field intensity between each hole and disk was observed in the simulations. The device is expected to be well-suited for optical trapping applications.
