Chirality encoding in resonant metasurfaces governed by lattice symmetries
Ivan Sinev, Felix Ulrich Richter, Ivan Toftul +6
Chiral metasurfaces provide invaluable tools capable of controlling structured light required for biosensing, photochemistry, holography, and quantum photonics. Here we suggest and…
Optical Supertorque Induced by Mie-Resonant Modes
Ivan Toftul, Mihail Petrov, Romain Quidant +1
We introduce the concept of resonant optical torque that allows enhancing substantially a transfer of optical angular momentum (AM) of light to a subwavelength particle. We conside…
Chiral Dichroism in Resonant Metasurfaces with Monoclinic Lattices
Ivan Toftul, Pavel Tonkaev, Kirill Koshelev +4
We demonstrate that chiral response can be achieved in resonant metasurfaces with a monoclinic lattice symmetry (the so-called Bravais oblique lattices) where the mirror symmetry i…
Nonlinear chiral metasurfaces based on structured van der Waals materials
Pavel Tonkaev, Ivan Toftul, Zhuoyuan Lu +6
Nonlinear chiral photonics explores nonlinear response of chiral structures, and it offers a pathway to novel optical functionalities not accessible through linear or achiral syste…
Transfer Matrix Approach for Topological Edge States
Rickson Wielian, Ivan Toftul, Yuri Kivshar
We suggest and develop a novel approach for describing topological properties of a periodic system purely from the transfer matrix associated to a unit cell. Our approach uses the…
Switchable optical trapping of Mie-resonant phase-change nanoparticles
Libang Mao, Ivan Toftul, Sivacarendran Balendhran +3
Optical tweezers revolutionized the manipulation of nanoscale objects. Typically, tunable manipulations of optical tweezers rely on adjusting either the trapping laser beams or the…
