Paper Abstract

A novel plasmonic Raman sensor using periodic nano-hole and, potentially, nanofocusing arrays is investigated numerically and experimentally. The effect of structural parameters (such as periodicity of the structure, hole dimensions, etc.) is determined and investigated. The analysed structures are fabricated in thin gold films by means of focused ion beam lithography. Optical characteristics of the fabricated arrays are determined experimentally and compared with the theoretical predictions. Experimental field enhancements are determined and also compared with the theoretical predictions.
