Optical Control of Chirality by Ultrafast Symmetry Breaking in Membrane Metasurfaces
Nikita Glebov, Alena Mamonova, Olesia Pashina +7
Chirality underpins a wide range of light-matter interactions, yet methods for its dynamic control in photonic systems remain limited. Here, we demonstrate ultrafast all-optical co…
