We investigated the effects of cross sectional geometry on surface plasmon polariton propagation in gold nanowires (NWs) using bleach-imaged plasmon propagation and electromagnetic simulations. Chemically synthesized NWs have pentagonally twinned crystal structures, but recent advances in synthesis have made it possible to amplify this pentagonal shape to yield NWs with a five-pointed-star cross section and sharp end tips. We found experimentally that NWs with a five-pointed-star cross section…

Dye-assisted gain of strongly confined surface plasmon polaritons in silver nanowires.
TLDR
The demonstration of gain for subwavelength SPPs that were strongly confined in chemically prepared silver nanowires using a dye-doped polymer film as the optical gain medium represents a major step forward toward the realization of nanoscale plasmonic amplifiers and lasers.
Visualization of Surface Plasmons Propagating at the Buried Organic-Metal Interface with Silver Nanocluster Sensitizers.
TLDR
The 2P-PEEM is applicable to the imaging of SPPs for thick C60/Au(111) interfaces, where SPP properties are hardly modulated by the added small amount (~0.1 monolayer) of Agn sensitizers.

Propagation lengths and group velocities of plasmons in chemically synthesized gold and silver nanowires.
TLDR
The measured propagation characteristics agree with numerical simulations, indicating that propagation in these wires is dominated by the material properties of the metals, with additional losses due to scattering from roughness or grain boundaries providing at most a minor contribution.
Identification of higher order long-propagation-length surface plasmon polariton modes in chemically prepared gold nanowires.
TLDR
It is suggested that caution must be taken in selecting indirect measurement techniques for probing SPP propagation in nanoscale metallic waveguides, especially to the difference in thickness of the dye layer coating on the nanowire.
Direct photonic–plasmonic coupling and routing in single nanowires
TLDR
It is demonstrated that SPPs can be excited simply by contacting a silver nanowire with a SnO2 nanoribbon that serves both as an unpolarized light source and a dielectric waveguide, which makes it possible to measure the propagation-distance-dependent waveguide spectra and frequency-dependent propagation length on a single Ag nanowires.
Imaging symmetry-selected corner plasmon modes in penta-twinned crystalline Ag nanowires.
TLDR
The results show that, beyond dissipation concerns, the morphological and structural control obtained in crystalline colloidal plasmonic nanostructures can be exploited to finely tune their optical properties.
Optimizing substrate-mediated plasmon coupling toward high-performance plasmonic nanowire waveguides.
TLDR
It is shown that leaky radiation can be blocked and high-performance plasmonic waveguiding can be extended to the near-infrared region by simply adding a high-permittivity layer onto the low-permitta substrate.
