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…
Engineering Magnetization with Photons: Nanoscale Advances in the Inverse Faraday Effect for Metallic and Plasmonic Systems
Chantal Hareau, Xingyu Yang, Maria Sanz +2
The inverse Faraday effect, the ability of light to act as a source of magnetism, is a cornerstone of modern ultrafast optics. Harnessing this effect at the nanoscale promises to t…
Twisting Light, Steering Spins: Gold Nanoparticle Magnetization via Inverse Faraday and Orbital Angular Momentum
Xingyu Yang, Chantal Harreau, Mathieu Mivelle
We present a new approach to controlling magnetization in gold nanoparticles using the Inverse Faraday Effect combined with Laguerre-Gauss beams carrying orbital angular momentum.…
Light-Driven Skyrmion Crystal Generation in Plasmonic Metasurfaces Through the Inverse Faraday Effect
Xingyu Yang, Chantal Hareau, Tristan da Câmara Santa Clara Gomes +2
Skyrmions are topological structures defined by a winding vector configuration that yields a quantized topological charge. In magnetic materials, skyrmions manifest as stable, mobi…
Evolutionary optimization of all-dielectric magnetic nanoantennas
Nicolas Bonod, Sebastien Bidault, Geoffrey W. Burr +1
Magnetic light and matter interactions are generally too weak to be detected, studied and applied technologically. However, if one can increase the magnetic power density of light…
Fiber-integrated single photon source of high efficiency based on a concept of ultra-broadband optical horn antenna
T. Grosjean, M. Mivelle, G. W. Burr +1
We theoretically demonstrate a fiber-integrated single photon source of unprecedented efficiency. This fiber single photon source is achieved by coupling optically a single quantum…
