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…
Extreme Huygens' metasurfaces based on quasi-bound states in the continuum
Mingkai Liu, Duk-Yong Choi
We introduce the concept and a generic approach to realize Extreme Huygens' Metasurfaces by bridging the concepts of Huygens' conditions and optical bound states in the continuum.…
Third-harmonic generation in photonic topological metasurfaces
Daria Smirnova, Sergey Kruk, Daniel Leykam +3
We study nonlinear effects in two-dimensional photonic metasurfaces supporting topologically-protected helical edge states at the nanoscale. We observe strong third-harmonic genera…
Highly localized Brillouin scattering response in a photonic integrated circuit
Atiyeh Zarifi, Birgit Stiller, Moritz Merklein +6
The interaction of optical and acoustic waves via stimulated Brillouin scattering (SBS) has recently reached on-chip platforms, which has opened new fields of applications ranging…
