Enabling all-to-circular polarization upconversion by nonlinear chiral metasurfaces with rotational symmetry
Dmitrii Gromyko, Jun Siang Loh, Jiangang Feng +2
We implement a stacking strategy in designing chiral metasurfaces with high rotational symmetry, enabling quasi-bound-in-the-continuum (quasi-BIC) resonances characterized by absol…

Unidirectional Chiral Emission via Twisted Bi-layer Metasurfaces
Dmitrii Gromyko, Shu An, Sergey Gorelik +8
Controlling and channelling light emissions from unpolarized quantum dots into specific directions with chiral polarization remains a key challenge in modern photonics. Stacked met…
