Optical nonlinearity goes ultrafast in 2D semiconductor-based nanocavities.

Published in: Light, science & applications (2022)

Hybrid systems of silver nanodisks strongly coupled to monolayer tungsten-disulfide (WS 2 ) show giant room-temperature nonlinearity due to their deeply sub-wavelength localized nature, resulting in ultrafast modifications of nonlinear absorption in a solid-state system.
