Abstract

A fast and accurate approach to find hybrid plasmonic waveguide mode and its properties is presented in this paper. The method is based on rational function fitting of spectral Green’s function of layered hybrid plasmonic waveguide with the use of modified VECTFIT algorithm. Complex modes including surface plasmonic modes of structures with insulator/metal loss can be obtained. The main advantage of this method lies in its simple implementation, speed as well as controllable accuracy. Effective index and propagation length versus thickness of layers are evaluated and excellent agreements with rigorous COMSOL solution (finite element method) are shown.
