Paper Abstract

We present a novel three-dimensional nano-hole array structure in an optically thick gold film, which benefits from Surface Plasmon (SP) energy matching between the top and bottom of the gold film. We have experimentally evaluated both a conventional and an SP energy-matched nano-hole array structure for Surface Plasmon Resonance (SPR) sensing. Also, detection of various bulk refractive index liquids has been tested for both structures based on the transmission intensity differences in a narrow detection band. We observed a 2-fold higher sensitivity during SPR sensing with the new structure compared to a conventional nano-hole array.
