Revealing a mode interplay that controls second harmonic radiation in gold nanoantennas
Jérémy Butet, Gabriel D. Bernasconi, Marlène Petit +5
In this work, we investigate the generation of second harmonic light by gold nanorods and demonstrate that the collected nonlinear intensity depends upon a phase interplay between…
Advanced engineering of single-crystal gold nanoantennas
R. Méjard, A. Verdy, O. Demichel +7
A nanofabrication process for realizing optical nanoantennas carved from a single-crystal gold plate is presented in this communication. The method relies on synthesizing two-dimen…
Energy-resolved hot carrier relaxation dynamics in monocrystalline plasmonic nanoantennas
Régis Méjard, Anthonin Verdy, Marlène Petit +3
Hot carriers are energetic photo-excited carriers driving a large range of chemico-physical mechanisms. At the nanoscale, an efficient generation of these carriers is facilitated b…
Dynamics, effciency and energy distribution of nonlinear plasmon-assisted generation of hot carriers
O. Demichel, M. Petit, S. Viarbitskaya +6
We employ nonlinear autocorrelation measurements to investigate plasmon-assisted hot carrier dynamics generated in optical gold antennas. We demonstrate that surface plasmons enabl…
Selective excitation of bright and dark plasmonic resonances of single gold nanorods
O. Demichel, M. Petit, G. Colas des Francs +5
Plasmonic dark modes are pure near-field resonances since their dipole moments are vanishing in far field. These modes are particularly interesting to enhance nonlinear light-matte…
Generation of two-dimensional plasmonic bottle beams
Patrice Genevet, Jean Dellinger, Romain Blanchard +6
By analogy to the three dimensional optical bottle beam, we introduce the plasmonic bottle beam: a two dimensional surface wave which features a lattice of plasmonic bottles, i.e.…
