Abstract

Linear arrays of plasmonic nanoparticles have been suggested by various groups as optical waveguides. Here, inspired by the concept of optical nanocircuits, we show that it is possible to improve the performance of such waveguide chains by pairing two of them, forming a two-wire optical transmission line. We show that choosing the operation regime near the light line may greatly reduce the effect of material absorption and disorder, still allowing field confinement in between the paired chains. Application for low-loss optical interconnects and subwavelength imaging devices are envisioned.
