TitleDesign of novel graphene-waveguide sensor
Untitled
Abstract

The plasmon characteristics in multilayer grapheme film sandwiched by anisotropic dielectric and water cover have been investigated. The dispersion relation for the plasmon waves is obtained analytically and the behaviour of the guided modes are discussed under three distinct cases. It is found that the penetration depth of surface plasmons is highly dependent with the surrounding dielectrics and oriented optical axis. The sensitivity has also been obtained. The sensitivity is proven to be affected by different parameters including the graphene thickness, the operating frequency, and the oriented optical axis. Higher sensitivity have been obtained by tuning some physical parameters. The results may be helpful for the practical application of graphene-based optoelectronic sensors.
