Nonlinear imaging of nanoscale topological corner states
Sergey S. Kruk, Wenlong Gao, Duk-Yong Choi +3
Topological states of light represent counterintuitive optical modes localized at boundaries of finite-size optical structures that originate from the properties of the bulk. Being…

High-harmonic generation from metasurfaces empowered by bound states in the continuum
George Zograf, Kirill Koshelev, Anastasia Zalogina +9
The concept of optical bound states in the continuum (BICs) underpins the existence of strongly localized waves embedded into the radiation spectrum that can enhance the electromag…
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…
Universal light-guiding geometry for high-nonlinear resonators having molecular-scale roughness
Dae-Gon Kim, Sangyoon Han, Joonhyuk Hwang +8
By providing an effective way to leverage nonlinear phenomena in chip-scale, high-Q optical resonators have induced the recent advances of on-chip photonics represented by micro-co…
Nonlinear metasurfaces governed by bound states in the continuum
Kirill Koshelev, Yutao Tang, Kingfai Li +3
Nonlinear nanostructured surfaces provide a paradigm shift in nonlinear optics with new ways to control and manipulate frequency conversion processes at the nanoscale, also offerin…
