Electrostatic control over optically-pumped hot electrons in optical gap antennas
Adrian Agreda, Sviatlana Viarbitskaya, Igor V. Smetanin +3
We investigate the influence of a static electric field on the incoherent nonlinear response of an unloaded electrically-contacted nanoscale optical gap antenna. Upon excitation by…
Designing plasmonic eigenstates for optical signal transmission in planar channel devices
Upkar Kumar, Sviatlana Viarbitskaya, Aurélien Cuche +6
On-chip optoelectronic and all-optical information processing paradigms require compact implementation of signal transfer for which nanoscale surface plasmons circuitry offers rele…
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…
Delocalization of nonlinear optical responses in plasmonic nanoantennas
Sviatlana Viarbitskaya, Olivier Demichel, Benoit Cluzel +2
Remote excitation and emission of two-photon luminescence and second-harmonic generation are observed in micrometer long gold rod optical antennas upon local illumination with a ti…
