Asymmetric high-harmonic generation from subwavelength bianisotropic resonators
Albert Mathew, Piyush Jangid, Rebecca Aschwanden +3
High-harmonic generation (HHG) enables attosecond light pulses and table-top sources of coherent extreme-ultraviolet and soft X-ray radiation. Although HHG has long been associated…

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…

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…
