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…
Improving the Transmittance of an Epsilon-Near-Zero based Wavefront Shaper
G. Briere, B. Cluzel, O. Demichel
Although Epsilon-Near-Zero metamaterials (ENZ) offer many unconventional ways to play with light, the optical impedance mismatch with surroundings can limit the efficiency of futur…
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…
Near-field properties of plasmonic nanostructures with high aspect ratio
Y. Ould Agha, O. Demichel, C. Girard +2
Using the Green's dyad technique based on cuboidal meshing, we compute the electromagnetic field scattered by metal nanorods with high aspect ratio. We investigate the effect of th…
