Energy intensity analysis of modes in hybrid plasmonic waveguide

Abstract

A hybrid plasmonic waveguide containing silicon core, silver cap and ultra-thin sandwiched SiO₂ layer is studied. By analyzing the mode distribution patterns and the curves of mode effective index, we show how the plasmonic mode around the metal surface is coupled with the fundamental mode in the silicon core to form a squeezed hybrid mode. The ability of the hybrid plasmonic waveguide in energy confinement is also discussed quantitatively.
