Paper Abstract

In this work, we report the experimental and numerical study of second harmonic generation (SHG) from Si-surface with randomly distributed Au-nanorods. The dependence of plasmonic resonance frequency was studied numerically for the gold nanorod-silicon dioxide-silicon substrate system as a function of nanorod sizes and dioxide film thickness. The numerical results demonstrate a high sensitivity of plasmonic resonance on the silicon dioxide thickness at the range up to 6 nm. We measured experimentally the dependencies of second harmonic signal as functions of the polarization angle of the pump beam from randomly distributed Au-nanorods on the Si-surface.
