Nonlinear imaging of nanoscale topological corner states
Sergey 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…
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…
Topological states in disordered arrays of dielectric nanoparticles
Ling Lin, Sergey Kruk, Yongguan Ke +2
We study the interplay between disorder and topology for the localized edge states of light in topological zigzag arrays of resonant dielectric nanoparticles. We characterize topol…
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…
