Plasmonic crystal waveguides

Abstract

We study the properties of electromagnetic waves propagating along the waveguides with a periodic core created by alternating metal and dielectric layers, the so-called quasi-one-dimensional plasmonic crystal waveguides. Such waveguides can be symmetric or asymmetric, depending on the cladding or substrate material properties, as well as on the termination of the periodic structure.We analyze the dispersion characteristics as well as the profiles of the guided modes for several types of waveguide structure.
