Abstract: (2172 Views)
In this paper, impact of V-grooves designed in core region of dielectric loaded graphene surface plasmon waveguide has been investigated for enhancement of sensing performance. According to the simulation results, it has been shown that the V-grooves increase the interaction of analyte with plasmonic field of the waveguide and improve propagation length of guided modes. Therefore, biosensor based-on the proposed graphene plasmonic waveguide with two symmetrical V-grooves demonstrates longer propagation length and higher sensitivity as compared with the conventional dielectric loaded graphene plasmonic waveguide.
