ABSTRACT
Resonant optical nanoantennas exhibit a different length scaling due to the surface plasmons compared to their radio frequency counterparts. In this letter, we address this difference by calculating the wavelength-dependent effective mode index neff for a cylindrical one-dimensional gold nanowire waveguide. Our results show that nanorod optical antennas act as dispersive and lossy Fabry–Pérot resonators for surface plasmons.

    Dielectric thin film stripes on a metal surface can be applied as surface plasmon (SP) waveguides. Here, the authors demonstrate experimentally that such structures can be used to build SP waveguide bends and couplers. On one hand, they show that SP transmission through a waveguide bend can be...

    We propose a compact 1-mm-radius microring resonator sensor based on a hybrid plasmonic waveguide on a silicon-on-insulator substrate. The hybrid waveguide is composed of a metal-gap-silicon structure, where the optical energy is greatly enhanced in the narrow gap. We use the finite element...

    In this paper, a novel metal-dielectric waveguide structure is proposed to support hybrid long range surface plasmon polaritons (LRSPPs) with a highly confined mode field.
