Topological plasmonic one-dimensional nanocavity
Abstract In this paper, we propose a topological plasmonic 1D nanocavity, which comprises a dielectric nanoparticle chain placed on a metallic substrate. The structure is designed based on the topological characteristics of the plasmonic photonic crystals. A topological edge state exists at the interface between two distinct structures. In comparison to a non-topological defect mode, the topological edge mode exhibits better properties including good confinement and robustness against perturbations in scales and length–width ratio of the nanoparticles.
