Photosensitive chalcogenide metasurfaces supporting bound states in the continuum
Elena Mikheeva, Kirill Koshelev, Duk-Yong Choi +6
We study, both theoretically and experimentally, tunable metasurfaces supporting sharp Fano-resonances inspired by optical bound states in the continuum. We explore the use of arse…
Individual nanoantennas empowered by bound states in the continuum for nonlinear photonics
Kirill Koshelev, Sergey Kruk, Elizaveta Melik-Gaykazyan +4
Bound states in the continuum (BICs) represent localized modes with energies embedded in the continuous spectrum of radiating waves. BICs were discovered initially as a mathematica…
Single-particle Mie-resonant all-dielectric nanolasers
Ekaterina Yu. Tiguntseva, Kirill L. Koshelev, Aleksandra D. Furasova +7
All-dielectric subwavelength structures utilizing Mie resonances provide a novel paradigm in nanophotonics for controlling and manipulating light. So far, only spontaneous emission…
Nonradiating Photonics with Resonant Dielectric Nanostructures
Kirill Koshelev, Gael Favraud, Andrey Bogdanov +2
Nonradiating sources of energy have traditionally been studied in quantum mechanics and astrophysics, while receiving a very little attention in the photonics community. This situa…
Enhanced second-harmonic generation with structured light in AlGaAs nanoparticles governed by magnetic response
Elizaveta V. Melik-Gaykazyan, Kirill L. Koshelev, Jae-Hyuck Choi +4
We employ structured light for the second-harmonic generation from subwavelength AlGaAs nanoparticles that support both electric and magnetic multipolar Mie resonances. The vectori…
Meta-optics and bound states in the continuum
Kirill Koshelev, Andrey Bogdanov, Yuri Kivshar
We discuss the recent advances in meta-optics and nanophotonics associated with the physics of bound states in the continuum (BICs). Such resonant states appear due to a strong cou…
