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…

Maximal optical chirality via mode coupling in bilayer metasurfaces

Brijesh Kumar, Ivan Toftul, Anshuman Kumar +2

Recent advances in the physics of resonant optical metasurfaces allowed to realize the so-called maximum chirality of planar structures by engineering their geometric parameters. H…

Chiral Nonlinear Polaritonics with van der Waals Metasurfaces

Connor Heimig, Alexander A. Antonov, Dmytro Gryb +10

In the strong-coupling regime, the interaction between light and matter reaches a hybridization state where the photonic and material components are inseparably linked. Using tailo…

Substrate-induced maximum optical chirality of planar dielectric structures

Maxim V. Gorkunov, Alexander A. Antonov, Alena V. Mamonova +2

Resonant dielectric planar structures can interact selectively with light of particular helicity thus providing an attractive platform for chiral flat optics. The absence of mirror…
