Crossing of the branch cut: the topological origin of a universal 2π-phase retardation in non-Hermitian metasurfaces
Rémi Colom, Elena Mikheeva, Karim Achouri +5
Full wavefront control by photonic components requires that the spatial phase modulation on an incoming optical beam ranges from 0 to 2π. Because of their radiative coupling to the…

Photosensitive chalcogenide metasurfaces supporting bound states in the continuum
Elena Mikheeva, Kirill Koshelev, Duk-Yong Choi +6
We study, both theoretically and experimentally, tunable metasurfaces supporting sharp Fano-resonances inspired by optical bound states in the continuum. We explore the use of arse…
