Plasmonic waveguiding in a hexagonally ordered metal wire array
TLDR
Simulation results show that hybridization of the single-wire mode and the gap plasmon mode can yield a hybrid mode with optimum propagation lengths comparable to those reported for other structures but with better light confinement.Abstract:
We propose the inclusion of a structured pattern of nanoscale metal wires in a silica fiber to form a symmetric plasmonic waveguide. The surface plasmon polariton modes within the waveguide are studied by varying the wire diameter and spacing. Simulation results show that hybridization of the single-wire mode and the gap plasmon mode can yield a hybrid mode with optimum propagation lengths comparable to those reported for other structures but with better light confinement. The fiber can be easily doped with a gain material to offset the loss so that the resultant waveguide will be useful for integration with electronic circuits at nanometer dimensions.read more

Excitation of a nanowire “molecule” in gold-filled photonic crystal fiber
TL;DR: A pair of gold nanowires, incorporated into a photonic crystal fiber, acts as a plasmonic "molecule" that forms bonding and antibonding solutions that results in a modal splitting of more than 100 nm, even though the spatial separation between the wires is larger than 3 μm.

Dispersion relation, propagation length and mode conversion of surface plasmon polaritons in silver double-nanowire systems.
TL;DR: Interestingly, in addition to the well studied gap mode, the other mode from group 1 which is a symmetrically coupled charge mode (mode 2) is found to have a larger group velocity and a longer propagation length than mode 1, suggesting mode 2 to be another potential signal transporter for plasmonic circuits.

Dispersion relation, propagation length and mode conversion of surface plasmon polaritons in silver double-nanowire systems
TL;DR: In this paper, the surface plasmon modes in a double-nanowire system were analyzed by employing the eigenmode analysis approach based on the finite element method and the dispersion relations, surface charge distributions, field patterns and propagation lengths of ten lowest energy plasmmon modes were presented.

Surface plasmon subwavelength optics
TL;DR: By altering the structure of a metal's surface, the properties of surface plasmons—in particular their interaction with light—can be tailored, which could lead to miniaturized photonic circuits with length scales that are much smaller than those currently achieved.
