Nanowire Plasmon Excitation by Adiabatic Mode Transformation

We show with both experiment and calculation that highly confined surface plasmon polaritons can be efficiently excited on metallic nanowires through the process of mode transfo...

Polarization-Selective Plasmon-Enhanced Silicon Quantum-Dot Luminescence

The photoluminescence intensity of silicon quantum dots is enhanced in a polarization-selective way by coupling to elongated Ag nanoparticles. The observed polarization dependen...

Complex response and polariton-like dispersion splitting in periodic metal nanoparticle chains

We show that guiding of optical signals in chains of metal nanoparticles is subject to a surprisingly complex dispersion relation. Retardation causes the dispersion relation to ...
