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…
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…
Optical chirality of membrane metasurfaces with broken in-plane symmetry
Ivan Toftul, Brijesh Kumar, Maxim Gorkunov +1
We study chiroptical properties of single-layer dielectric membrane metasurfaces with broken in-plane symmetry. In sharp contrast to a common belief that chiral optical phenomena r…
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…
