Abstract

Zinc oxide is a wide-bandgap semiconductor material, which can be grown as a single crystal and also as a thin film. A gold nanowire with zinc oxide cladding can serve as a waveguide, which can combine the plasmonic features of a metal nanowire with the sensing properties of ZnO. Using an H-field-based fully vectorial finite element method, rigorous modal solutions for the characteristics of a gold nanowire core with zinc oxide cladding are obtained. The modal properties, including the effective index, spot size, confinement factor, and modal hybridness have been analyzed to determine the fundamental plasmonic mode of this waveguide.
