ATTOSECOND PHOTONICS

Nanoantenna tunnelling currents record laser waves

Nature Photonics volume 15, pages 408–410 (2021)Cite this article

Subjects

Tunnelling currents inside plasmonic nanostructures are fast enough to gain direct access to the oscillating electric field of near-infrared and visible light, opening up exciting routes towards attosecond metrology of light–matter interaction and unique approaches to spectroscopy.
