Abstract

Based on the exact solution of Maxwell’s equations and numerical calculations, we have investigated the basic theoretical properties of metal-coated silica nanowires. Modal profile, field and power distributions, and conditions for surface plasmon excitation are studied. It shows that a thin layer of metal coat can influence the distribution of the electromagnetic field and enhance confinement ability of light power inside silica core due to its negative dielectric function, which may be favorable for reducing the size of wire waveguide for microphotonic applications.
