Propagation of light in serially coupled plasmonic nanowire dimer: Geometry dependence and polarization control

Directional Fluorescence Emission Mediated by Chemically-Prepared Plasmonic Nanowire Junctions

“…They have also been studied in context of directed fluorescence emission for building optical devices . An advantage of serially coupled silver (Ag) nanowires (NW) is that they facilitate SPPs and LSP on the same platform. , A highly localized field can be produced at the fused-junction while illuminating either of the free ends. Such junctions can further serve as a hotspot for remote excitation of molecular spectroscopy. , We further use this advantage to direct fluorescence emission.…”

Coherent Control of Plasmon Propagation in a Nanocircuit

“…The control can rather also be part of the source. First experiments to manipulate propagating plasmons have been performed by using networks of chemically grown silver nanowires [12][13][14][15][16][17] or slotless gold nanostructures [18]. However, only recent advances in the understanding and fabrication of plasmonic nanocircuits based on optical antennas [19,20] and two-wire transmission lines [21,22] have enabled the quantitative selective excitation of multiple eigenmodes [23].…”

Shape Restoration Effect in Ag–SiO2 Core–Shell Nanowires

“…In flexible coatings, , as well as in nanorelays, nanoswitches, and nanoresonators, NWs must be able to withstand numerous repetitive deformations. In nanophotonics, a significant degree of bending is often required in order to guide the light in the desired direction . It has also been shown that defects or discontinuitiessuch as cracks introduced by bending of Ag NWsstrongly affect the light propagation in waveguides. , Therefore, the improvement of mechanical properties is essential for performance and reliability in the applications described above.…”
