Phase-Flow Topology of Bound States in the Continuum
Nikolai A. Vlasov, Varvara P. Panurchenko, Ravshanjon Kh. Nazarov +3
Control of topological charges of bound states in the continuum (BICs) is essential for advanced topological photonics. A rigorous theoretical framework for understanding the forma…
A complete photoluminescence polarization palette from a photonic-crystal slab
A. V. Peretokin, M. V. Stepikhova, N. A. Gippius +6
Integrated light sources with tailored polarization are essential for integrated photonics, optical communication, sensing, and structured-light applications. However, generating a…
Bound states in the continuum in a chain of coupled Mie resonators with structural disorder: theory and experiment
Ravshanjon Nazarov, Denis Khanabiev, Elizaveta Chernysheva +7
We study the impact of structural disorder on a radiative lifetime of symmetry-protected bound state in the continuum (BIC) and a bright mode in a one-dimensional periodic chain of…
Emergence of collective spectral features in finite arrays of dielectric rods
Ilya Karavaev, Ravshanjon Nazarov, Yicheng Li +2
Periodic optical structures, such as diffraction grating and numerous photonic crystals, are one of the staples of modern nanophotonics for the manipulation of electromagnetic radi…
