Plasmonic Fourier Surfaces Revisited: Relating Bandgaps with Bound States in the Continuum
Alexander A. Antonov, Connor Heimig, Hannah Niese +5
Periodically corrugated metal interfaces supporting surface plasmon polaritons (SPPs) belong to the earliest nanoplasmonic platforms. Even simplest reliefs described by a few harmo…
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…
Rewritable Chirality of Metasurfaces with Permittivity-Asymmetric Flatband Quasi-Bound States in the Continuum
Tao Jiang, Haiyang Hu, Dmytro Gryb +4
Flatband eigenstates are widely applied to enhance angle-robust light-matter interactions in metaphotonics. However, controlling the polarization of flatbands remains challenging,…
Topological Control of Polaritonic Flatbands in Anisotropic van der Waals Metasurfaces
Connor Heimig, Thomas Weber, Cristina Cruciano +9
Anisotropic van der Waals (vdW) materials exhibit direction-dependent optical and electronic properties, making them valuable for tailoring directional light-matter interactions. R…
Observation of Janus Chirality for Coherent Thermal Emission from Metasurfaces
Kaili Sun, Yangjian Cai, Maxim V. Gorkunov +2
Metasurfaces emerged as a powerful tool for controlling thermal radiation, yet achieving coherent emission with opposite circular handednesses remains a highly challenging problem.…
Nonlinear chiral light generation from resonant metasurfaces
Fangxing Lai, Jun Yin, Ivan Toftul +6
Chiral nonlinear response has been explored for decades due to its extreme sensitivity to molecular and structural dissymmetry. Conventional approaches often require bulky systems…
