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…

Lower bound for the spatial extent of localized modes in photonic-crystal waveguides with small random imperfections
Rémi Faggiani, Alexandre Baron, Xiaorun Zang +8
Light localization due to random imperfections in periodic media is paramount in photonics research. The group index is known to be a key parameter for localization near photonic b…
