Metaphotonics for High-Harmonic Generation
Pavel Tonkaev, Anton Rudenko, Ziwen Wang +2
We summarise the recent advances on the generation of high-order harmonics in optical metaphotonic structures such as isolated resonators and metasurfaces. In such subwavelength-pa…

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…
