Abstract

Third harmonic generation microscopy of hexagonal arrays of amorphous silicon nanodisks with resonance at fundamental wavelength is presented. The onset and progression of intensity and spatially dependent saturation effects are clearly observed through the contrast reversal of third harmonic generation signal generated at the nanodisks.
