All-optical directional switching of non-thermal photocurrents in plasmonic nanocircuits
Roméo Zapata, Diana Singh, Obren Markovic +9
Controlling the flow of electricity in metallic circuits with light is a key goal for future optoelectronics. In this work, we demonstrate all-optical generation and directional co…
Control of light emission of quantum emitters coupled to silicon nanoantenna using cylindrical vector beams
Martin Montagnac, Yoann Brûlé, Aurélien Cuche +11
Light emission of europium (Eu3+) ions placed in the vicinity of optically resonant nanoantennas is usually controlled by tailoring the local density of photon states (LDOS). We sh…
Magnetic and electric Purcell factor control through geometry optimization of high index dielectric nanostructures
Yoann Brûlé, Peter R. Wiecha, Aurélien Cuche +2
We design planar silicon antennas for controlling the emission rate of magnetic or electric dipolar emitters. Evolutionary algorithms coupled to the Green Dyadic Method lead to dif…

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…
Spontaneous hot-electron light emission from electron-fed optical antennas
Mickael Buret, Alexander V. Uskov, Jean Dellinger +7
Nanoscale electronics and photonics are among the most promising research areas providing functional nano-components for data transfer and signal processing. By adopting metal-base…
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…
