We design and fabricate individual subwavelength AlGaAs nanoantennas supporting Mie resonances in the mid-infrared spectral range. Near the resonant modes, we observe five-photon upconversion photoluminescence in the visible spectral range.

Abstract
We design and fabricate individual subwavelength AlGaAs nanoantennas supporting Mie resonances in the mid-infrared spectral range. Near the resonant modes, we observe five-photon upconversion photoluminescence in the visible spectral range.File in questo prodotto:
