Probing topological edge states in multilayer dielectric photonic nanostructures
Eva Otero, Ivan Toftul, Michael Scalora +3
Topological photonics has recently attracted a significant attention, leading to many theoretical studies and predictions. However, direct experimental demonstrations of topology-d…
Enhanced chiral response of hybrid photonic structures empowered by Mie resonances
Xingguang Liu, Wenzhe Hao, Ivan Toftul +3
Chiroptical response provides a powerful route to control light-matter interactions through light handedness, with crucial importance in polarization control, chiral sensing, and n…
Optical chirality of membrane metasurfaces with broken in-plane symmetry
Ivan Toftul, Brijesh Kumar, Yuri Kivshar
We study chiroptical properties of single-layer dielectric membrane metasurfaces with broken in-plane symmetry. Although chiral optics was long tied to structures lacking any mirro…
Intrinsic chirality of dielectric metasurfaces unlocked by resonant chiral modes
Brijesh Kumar, Pavel Tonkaev, Ivan Toftul +7
Controlling optical chirality at the subwavelength scales is essential for many applications of nanophotonic structures in polarization optics, sensing, and nonlinear photonics. Ac…
Nonlinear chiral response governed by meta-atom rotation
Dhruv Hariharan, Pavel Tonkaev, Felix Ulrich Brikh +5
Chiral photonics provides powerful routes for controlling the light handedness, yet nonlinear chiral responses are typically associated with intricate three-dimensional systems. He…
Nonlinear chiral light generation from resonant metasurfaces
Fangxing Lai, Jun Yin, Ivan Toftul +6
Chiral nonlinear response has been explored for decades due to its extreme sensitivity to molecular and structural dissymmetry. Conventional approaches often require bulky systems…
