We demonstrate all-optically tunable second-harmonic generation (SHG) in GaAs nanowires via nonlinear absorption. This approach enables near-infrared SHG modulation up to 60% and offers new opportunities for nonlinear applications and all-optical ultrafast modulation.

Abstract
We demonstrate all-optically tunable second-harmonic generation (SHG) in GaAs nanowires via nonlinear absorption. This approach enables near-infrared SHG modulation up to 60% and offers new opportunities for nonlinear applications and all-optical ultrafast modulation.File in questo prodotto:
