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…
Nonlinear chiral response from linearly achiral membrane metasurfaces
Pavel Tonkaev, Yeqi Zhuang, Donghwee Kim +9
Chiral photonics aims to control and engineer light handedness for many applications in optical communications, biological and chemical sensing, and quantum technologies. While tra…
Maximal optical chirality via mode coupling in bilayer metasurfaces
Brijesh Kumar, Ivan Toftul, Anshuman Kumar +2
Recent advances in the physics of resonant optical metasurfaces allowed to realize the so-called maximum chirality of planar structures by engineering their geometric parameters. H…
Hopping of nanoparticles in optical tweezers governed by Mie resonances
Ivan Toftul, Libang Mao, Sivacarendran Balendhran +3
Optical tweezers have become a standard tool for manipulating microscale and nanoscale particles and probing their local environments. However, complex particle dynamics under opti…
Unconventional high-harmonic generation in resonant membrane metasurfaces
Pavel Tonkaev, Felix Richter, Ivan Toftul +5
High-harmonic generation (HHG) in solids has rapidly emerged as a promising platform for creating compact attosecond sources and probing ultrafast electron dynamics. Resonant metas…
Monoclinic nonlinear metasurfaces for resonant engineering of polarization states
Ivan Toftul, Dhruv Hariharan, Pavel Tonkaev +3
Polarization is a fundamental property of light that can be engineered and controlled efficiently with optical metasurfaces. Here, we employ chiral metasurfaces with monoclinic lat…
Acoustic angular sorting of resonant subwavelength particles
Ivan Toftul, Yuri Kivshar, Mikhail Lapine
We suggest a dynamical mechanism for angular sorting of subwavelength particles in accord with their resonances and sizes, realised with the forces imposed by acoustic (ultrasound)…
