Surface second-harmonic generation from coupled spherical plasmonic nanoparticles: Eigenmode analysis and symmetry properties

Olivier Martin, Shourya Dutta Gupta, Jérémy Butet

The surface second-harmonic generation from interacting spherical plasmonic nanoparticles building different clusters (symmetric and asymmetric dimers, trimers) is theoretically investigated. The plasmonic eigenmodes of the nanoparticle clusters are first ...

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 ...

Metal Double Layers with Sub-10 nm Channels

Olivier Martin, Li Wang, Thomas Gerd Siegfried

Double-layer plasmonic nanostructures are fabricated by depositing metal at normal incidence onto various resist masks, forming an antenna layer on top of the resist post and a hole layer on the substrate. Antenna plasmon resonances are found to couple to ...

Periodicity-Induced Symmetry Breaking in a Fano Lattice: Hybridization and Tight-Binding Regimes

Olivier Martin, Chen Yan

We investigate experimentally and theoretically the role of periodicity on the optical response of dolmen plasmonic arrays that exhibit a Fano line shape. Contrary to previous works on single nanostructures, this study deals with the in-plane near-field co ...

Polarisation charges and scattering behaviour of realistically rounded plasmonic nanostructures

Olivier Martin

We study the effect of realistically rounding nanorod antennae and gap antennae on their far field and near field properties. The simulations show that both scattering behaviour and polarisation charge distribution depend significantly on rounding. Roundin ...
