We demonstrate optical switching of second harmonic generation (SHG) in AlGaAs nanoantennas. We observe more than 50% enhancement/suppression of the SHG excited at telecom wavelength when pumping above the material bandgap with a CW laser.

Abstract
We demonstrate optical switching of second harmonic generation (SHG) in AlGaAs nanoantennas. We observe more than 50% enhancement/suppression of the SHG excited at telecom wavelength when pumping above the material bandgap with a CW laser.File in questo prodotto:
