TitlePerformance and Sensitivity Enhancement of Four-Layered Planar Waveguide Sensors Containing Graphene: TM-Mode Case
Untitled
Abstract

We examine analytically the propagation of TM-polarized waves in a multilayered Graphene-Oxide-Silicon (GOS) slab waveguide structure covered by the sensing layer. One of the layers is considered as an infinitesimally thin graphene layer. Surface charge is assumed to be at the graphene/oxide interface. The dispersion relation and the sensitivity of the proposed structure have been derived theoretically and shown in terms of the waveguide thickness and other physical parameters. Higher sensitivity has been obtained by tuning some physical parameters. The results are useful for the practical application of graphene-based optoelectronic sensors.
