Abstract

The modal properties of a ZnO-coated nanosized Au waveguide have been determined and analyzed using the H-field-based full vectorial finite-element method. The effect of Al doping of ZnO on the modal properties of the waveguide designed has also been evaluated for its potential use in environmental monitoring.
