Topological membrane devices for terahertz on-chip photonics
Quanlong Yang, Dongyang Wang, Sergey Kruk +4
Terahertz waves offer a profound platform for next-generation sensing, imaging, and information communications. However, all conventional terahertz components and systems suffer fr…
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…
Topological nanophotonics for photoluminescence control
Aditya Tripathi, Sergey Kruk, Yunfei Shang +4
Rare-earth doped nanocrystals are emerging light sources used for many applications in nanotechnology enabled by human ability to control their various optical properties with chem…
Nonlinear imaging with all-dielectric metasurfaces
Christian Schlickriede, Sergey Kruk, Lei Wang +3
Nonlinear metasurfaces incorporate many of the functionalities of their linear counterparts such as wavefront shaping but simultaneously they perform nonlinear optical transformati…
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…
