摘要：

A new type of subwavelength plasmonic waveguide based on a core-shell structure has been proposed. It is based on a semicylinder-shape dielectric-loaded plasmonic waveguide supporting the excitation of surface plasmon polaritons (SPPs). Simulation results reveal that the proposed waveguide exhibit a better trade-off in terms of mode localization and propagation length when compared to the traditional dielectric-loaded plasmonic waveguide. In addition, a ring resonator formed with the proposed waveguide shows a perfect performance with 1.8nm bandwidth and 23dB extinction ratio.
