Symmetry-governed nonlinear metasurface simultaneously enhances circular dichroism, helicity purity, and Q-factor
Dmitrii Gromyko, Wenhe Jia, Chengfeng Pan +12
Circularly polarized light underpins a broad range of chiroptical and spin-selective photonic technologies, yet extending resonant chirality to nonlinear harmonic emission remains…
Crystal orientation enables near-unity nonlinear circular dichroism in resonant metasurfaces
Chi Wang, Dmitrii Gromyko, Polina Pantiukhina +2
Achieving near-unity nonlinear circular dichroism (CD) typically requires geometric symmetry breaking, making it challenging to combine helicity selectivity, resonant enhancement,…
Enhancing Volumetric Optical Chirality through 2D-3D Structural Design Evolution
Chia-Te Chang, Xiaoyan Zhou, Dmitrii Gromyko +6
Circular dichroism (CD) sensing plays a pivotal role in probing molecular chirality in biomedical sciences. However, engineering superchiral electromagnetic fields that can reliabl…
Light-cone-proximal quasi-BICs for chiral lasing at grazing angles
Dmitrii Gromyko, Cheng-Wei Qiu, Kirill Koshelev +1
Chiral quasi-bound states in the continuum (q-BICs) have recently emerged in metaphotonics as resonances that combine ultrahigh quality factors with near-unity circular polarizatio…
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…
Resonant mode approximation of the scattering matrix of photonic crystal slabs near several Wood-Rayleigh anomalies
Dmitrii Gromyko, Sergey Dyakov, Vladimir Zinovyev +2
The resonant mode approximation of the scattering matrix is considered for calculating the optical properties of multilayered periodic structures within the formalism of the Fourie…
