Paper Abstract

A novel surface plasmon polariton-based waveguide (or called plasmonic waveguide) is proposed to achieve millimeter-scale propagation distance while maintaining subwavelength mode area. For easy to practically fabricate, the proposed structure is consisted of a cylinder metallic nanowire bounded by a high-index contrast dielectric material on a low-index dielectric substrate. The cladding region of the proposed structure is air. To satisfy the index matching condition, we vary the thickness of the high-index dielectric above the cylinder nanowire. A symmetric mode field profile exhibiting the lowest resistive loss resulted from the metal is thus obtained to accomplish the low-loss propagation. The proposed plasmonic waveguide could offer plasmonic circuit interconnects and high-density integrated photonic circuits.
