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…
Resonant mode coupling approximation for calculation of optical spectra of photonic crystal slabs
Dmitrii A. Gromyko, Sergey A. Dyakov, Sergei G. Tikhodeev +1
We develop the resonant mode coupling approximation to calculate the optical spectra of a stack of two photonic crystal slabs. The method is based on a derivation of the input and…
