Abstract

Babinet-inverted plasmonic metasurfaces based on nanoapertures in Au film as nonlinear meta-atoms are attracting considerable interest. The nanoapertures cannot only improve the threshold for thermal damage, but also can efficiently suppress the background third harmonic generation (THG) radiation from the thick substrate and thus improve signal-to-noise ratio. Indeed, discernible harmonic radiation from Au nanostructures is crucial in some studies such as nonlinear beam shaping, nonlinear phase control and anomalous phase matching [1-3].
