Mode Analysis of Hybrid Metal-Insulator-Metal Multilayer Plasmonic Waveguide

Abstract

In order to explore the mode properties, such as effective mode index and propagation length of the hybrid metal-insulator-metal (HMIM) multilayer Plasmonic waveguide, the dimensions of the waveguide have been varied at the operating wavelength of 1550 nm under the constraint of light propagation through the low-index region. The mode analysis for the propagation of fundamental and higher order modes have been carried out in the current work to obtain the suitable dimension of the HMIM Plasmonic waveguide. The multimode propagation is an important aspect for the bio-sensor related applications.
