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…

Monoclinic nonlinear metasurfaces for resonant engineering of polarization states
Ivan Toftul, Dhruv Hariharan, Pavel Tonkaev +3
Polarization is a fundamental property of light that can be engineered and controlled efficiently with optical metasurfaces. Here, we employ chiral metasurfaces with monoclinic lat…

Chiral Dichroism in Resonant Metasurfaces with Monoclinic Lattices
Ivan Toftul, Pavel Tonkaev, Kirill Koshelev +4
We demonstrate that chiral response can be achieved in resonant metasurfaces with a monoclinic lattice symmetry (the so-called Bravais oblique lattices) where the mirror symmetry i…
