Report

Electrostatic control over optically-pumped hot electrons in optical gap antennas

Autor: Agreda, Adrian, Viarbitskaya, Sviatlana, Smetanin, Igor V., Uskov, Alexander V., Francs, Gérard Colas des, Bouhelier, Alexandre

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 a tightly focused near-infrared femtosecond laser beam, a transient e

Designing plasmonic eigenstates for optical signal transmission in planar channel devices

Autor: Kumar, Upkar, Viarbitskaya, Sviatlana, Cuche, Aurélien, Girard, Christian, Bolisetty, Sreenath, Mezzenga, Raffaele, Francs, Gérard Colas Des, Bouhelier, Alexandre, Dujardin, Erik

Publikováno v: ACS photonics, American Chemical Society, 2018, 5 (6), pp.2328 - 2335

On-chip optoelectronic and all-optical information processing paradigms require compact implementation of signal transfer for which nanoscale surface plasmons circuitry offers relevant solutions. This work demonstrates the directional signal transmit

Report

Delocalization of nonlinear optical responses in plasmonic nanoantennas

Autor: Viarbitskaya, Sviatlana, Demichel, Olivier, Cluzel, Benoit, Francs, Gérard Colas des, Bouhelier, Alexandre

Publikováno v: Phys. Rev. Lett. 115, 197401 (2015)

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 tightly focused near-infrared femtosecond laser beam. We show that the n

Resonance-enhanced Second Harmonic Generation from spherical microparticles in aqueous suspension

Autor: Viarbitskaya, Sviatlana

Second harmonic generation (SHG) is a nonlinear optical effect sensitive to interfaces between materials with inversion symmetry. It is used as an effective tool for detection of the adsorption of a substance to microscopic particles, cells, liposome
