Stacked chalcogenide metasurfaces for third harmonic generation in the UV range

Stacked chalcogenide metasurfaces for third harmonic generation in the UV range

We show that an appropriately designed chalcogenide metasurface allows the enhancement of harmonic generation in the UV range, a regime that conventional wisdom deems inaccessible because of absorption. Here we exploit a combination of the photonic band structure that forms when stacking As _2 S _3...
