Report

Dynamics, effciency and energy distribution of nonlinear plasmon-assisted generation of hot carriers

Autor: Demichel, O., Petit, M., Viarbitskaya, S., Mejard, R., de Fornel, F., Hertz, E., Billard, F., Bouhelier, A., Cluzel, B.

We employ nonlinear autocorrelation measurements to investigate plasmon-assisted hot carrier dynamics generated in optical gold antennas. We demonstrate that surface plasmons enable a nonlinear formation of hot carriers, providing thus a unique lever

Selective excitation of bright and dark plasmonic resonances of single gold nanorods

Autor: Demichel, O., Petit, M., Francs, G. Colas des, Bouhelier, A., Hertz, E., Billard, F., de Fornel, F., Cluzel, B.

Publikováno v: Optics Express Vol. 22, Issue 12, pp. 15088-15096 (2014)

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-matter interaction at the nanometer scale because radiative losses are miti

Photonic crystal carpet: Manipulating wave fronts in the near field at 1550 nm

Autor: Scherrer, G., Hofman, M., Śmigaj, W., Kadic, M., Chang, T. -M., Mélique, X., Lippens, D., Vanbésien, O., Cluzel, B., de Fornel, F., Guenneau, S., Gralak, B.

Ground-plane cloaks, which transform a curved mirror into a flat one, and recently reported at wavelengths ranging from the optical to the visible spectrum, bring the realm of optical illusion a step closer to reality. However, all carpet-cloaking ex
