We exploit the band structure of stacked chalcogenide metasurfaces to enhance harmonic generation in the ultra-violet frequency range. Suppression of absorption and improved field localization conspire to generate a third harmonic signal at ~285 nm.

Abstract
We exploit the band structure of stacked chalcogenide metasurfaces to enhance harmonic generation in the ultra-violet frequency range. Suppression of absorption and improved field localization conspire to generate a third harmonic signal at ~285 nm.File in questo prodotto:
