Abstract

A novel nanophotonic waveguide for light confinement in low-index media is reported in this paper. Waveguide modal properties have been evaluated by the 3D Finite Element Method. Dependence of both confinement factor and propagation length on waveguide size has been investigated. Finally, waveguide group velocity dispersion and waveguide sensitivity have been calculated. The numerical results we have achieved demonstrate the potential of the new plasmonic hollow waveguide as the key element of integrated optical biochemical sensors.
