Asymmetric high-harmonic generation from subwavelength bianisotropic resonators
Albert Mathew, Piyush Jangid, Rebecca Aschwanden +3
The paper demonstrates that a single subwavelength dielectric resonator with structural asymmetry can generate high-order harmonics preferentially in one direction, using the excit…
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…
Chiral high-harmonic generation in metasurfaces
Piyush Jangid, Maria Antonietta Vincenti, Luca Carletti +3
High-harmonic generation (HHG) provides the only source of attosecond pulses -- currently the shortest accessible time intervals, and it is employed as the only table-top source of…
Strong coupling and interfering resonances in isolated van der Waals nanoresonators
Qi Ding, Swain Ashutosh, Luca Sortino +7
The study of strong light-matter interaction in van der Waals materials is at the forefront of current research in physics and chemistry, and it can be enhanced dramatically by emp…
Nonreciprocal metasurfaces with epsilon-near-zero materials
Albert Mathew, Rebecca Aschwanden, Aditya Tripathi +4
Nonreciprocal optics enables asymmetric transmission of light when its sources and detectors are exchanged. A canonical example -- optical isolator -- enables light propagation in…
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…
