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…
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…
Wide-bandgap optical materials for high-harmonics generation at the nanoscale
Albert Mathew, Sergey Kruk, Shunsuke Yamada +2
High-order harmonics generation (HHG) is the only process that enables table-top-size sources of extreme-ultraviolet (XUV) light. The HHG process typically involves light interacti…
