Abstract

We present experimental results of linear and nonlinear optical measurements from a plasmonic metasurface composed by self-assembled tilted gold nanowires. We investigated the extrinsic chiral response due to the particular symmetry breaking induced by the nanowires geometry by using second harmonic generation, photoacoustic Absorption and optical reflectance measurements.
