Abstract

Waveguiding properties of linear 1D arrays of metal nanoparticles have recently attracted considerable attention. For applications in nanophotonics, integrated optical circuits, etc., the dispersive properties of surface plasmon polaritons (SPPs) in such waveguides are of primary importance and have been studied extensively in chains of spherical nanoparticles [1, 2]. The effects of nonsphericity although have been noted [3], received little attention. In the recent paper [4], we have demonstrated that using nanoparticles of nonspherical shape provides additional tunability and can lead to dramatic improvement of the waveguide quality, in particular, in a significant increase of the operating bandwidth.
