Large-scale sub-100 nm compound plasmonic grating arrays to control the interaction between localized and propagating plasmons

Olivier Martin, Arash Farhang, Thomas Gerd Siegfried

Compound plasmonic resonances arise due to the interaction between discrete and continuous metallic nanostructures. Such combined nanostructures provide a versatility and tunability beyond that of most other metallic nanostructures. In order to observe suc ...

Coupling of multiple LSP and SPP resonances: interactions between an elongated nanoparticle and a thin metallic film

Olivier Martin, Arash Farhang, Nicolas Bigler

We study the coupling interactions between a progressively elongated silver nanoparticle and a silver film on a glass substrate. Specifically, we investigate how the coupling between localized surface plasmons (LSPs) and propagating surface plasmon polarit ...

Multipolar effects and strong coupling in hybrid plasmonic metamaterials

Olivier Martin, Arash Farhang

Recently stacked metamaterial structures coupled to a conductive plane have been investigated and have been shown to exhibit the same properties as stacked structures with double the layers, due to dipole mirror coupling. Here we study a system of stacked ...

Hybrid nanoparticle and thin film SPR biosensor with a high figure of merit

Olivier Martin, Banafsheh Abasahl, Arash Farhang

Due to their extreme sensitivity to refractive index changes, surface plasmon resonance (SPR) sensors have long been established as extremely valuable tools for biosensing. In the past few years researchers have begun investigating various other metallic n ...

Compound resonance-induced coupling effects in composite plasmonic metamaterials

Olivier Martin, Arash Farhang

We study a compound plasmonic system composed of a periodic Au grating array placed close to a thin Au film. The study is not limited to normal incidence and dispersion diagrams are computed for a broad variety of parameters. In addition to identifying loc ...
