Enhanced five-photon photoluminescence in subwavelength AlGaAs resonators
Anastasiia Zalogina, Pavel Tonkaev, Aditya Tripathi +5
Multiphoton processes of absorption photoluminescence have enabled a wide range of applications including three-dimensional microfabrication, data storage, and biological imaging.…
Unlocking the out-of-plane dimension for photonic bound states in the continuum to achieve maximum optical chirality
Lucca Kühner, Fedja J. Wendisch, Alexander A. Antonov +7
The realization of lossless metasurfaces with true chirality crucially requires the fabrication of three-dimensional structures, constraining their feasibility for experiments and…
Nonlinearity-induced optical torque
Ivan Toftul, Gleb Fedorovich, Denis Kislov +4
Optically-induced mechanical torque leading to the rotation of small objects requires the presence of absorption or breaking cylindrical symmetry of a scatterer. A spherical non-ab…
Nanoscale optical nonreciprocity with nonlinear metasurfaces
Aditya Tripathi, Chibuzor Fabian Ugwu, Viktar S. Asadchy +6
Optical nonreciprocity is manifested as a difference in the transmission of light for the opposite directions of excitation. Nonreciprocal optics is traditionally realized with rel…
Plasmonic Bound States in the Continuum to Tailor Light-Matter Coupling
Andreas Aigner, Andreas Tittl, Juan Wang +4
Plasmon resonances play a pivotal role in enhancing light-matter interactions in nanophotonics, but their low-quality factors have hindered applications demanding high spectral sel…
High harmonic generation from a subwavelength dielectric resonator
Anastasiia Zalogina, Luca Carletti, Aditya Tripathi +5
Higher-order optical harmonics entered the realm of nanostructured solids being observed recently in optical gratings and metasurfaces with a subwavelength thickness. Structuring m…
Dielectric Mie Voids: Confining Light in Air
Mario Hentschel, Kirill Koshelev, Florian Sterl +6
Manipulating light on the nanoscale has become a central challenge in metadevices, resonant surfaces, nanoscale optical sensors, and many more, and it is largely based on resonant…
Magnetoelectric Exceptional Points in Isolated All-Dielectric Nanoparticles
Adrià Canós Valero, Vjaceslavs Bobrovs, Dmitrii Redka +2
We consider the scattering of electromagnetic waves by non-spherical dielectric resonators and reveal that it can be linked to the exceptional points underpinned by the physics of…
Optical manipulation with metamaterial structures
Yuzhi Shi, Qinghua Song, Ivan Toftul +6
Optical tweezers employing forces produced by light underpin important manipulation tools in many areas of applied and biological physics. Conventional optical tweezers are based o…
Resonant chiral effects in nonlinear dielectric metasurfaces
Kirill Koshelev, Yutao Tang, Zixian Hu +3
We study the resonant enhancement of linear and nonlinear chiroptical effects in asymmetric silicon metasurfaces supporting multipolar Mie resonances and quasi-bound states in the…
Topological membrane devices for terahertz on-chip photonics
Quanlong Yang, Dongyang Wang, Sergey Kruk +4
Terahertz waves offer a profound platform for next-generation sensing, imaging, and information communications. However, all conventional terahertz components and systems suffer fr…
