Nonlinear circular dichroism in Mie-resonant nanoparticle dimers
Kristina Frizyuk, Elizaveta Melik-Gaykazyan, Jae-Hyuck Choi +3
We study nonlinear response of a dimer composed of two identical Mie-resonant dielectric nanoparticles illuminated normally by a circularly polarized light. We develop a general th…
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…
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…
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…
Time-resolved spectroscopy with entangled photons
Dmitry A. Kalashnikov, Elizaveta V. Melik-Gaykazyan, Alexey A. Kalachev +3
Interaction of light with media often occurs with a femtosecond response time. Its measurement by conventional techniques requires the use of femtosecond lasers and sophisticated t…
