Second harmonic generation on self-assembled tilted gold nanowires

Abstract

Here we present measurements on a metasurface composed by tilted gold nanowires. The metasurface can induce an optical chiral response of the whole sample when the light impinges on the sample out of the normal incidence angle. In order to investigate the symmetry breaking induced by the geometry, we measured the second harmonic generation (SHG) signal generated by circular polarized pulsed light. This technique has demonstrated to be a powerful method in order to investigate the chiral morphology of nanostructures.
