Second harmonic generation from artificial metasurfaces
Here we discuss the second harmonic generation (SHG) signal raised by a sample surface manifesting circular dichroism. The measurement were performed by studying the SHG efficiency in different polarization states of the light. In particular measurement performed with circular polarized light showing a very high sensitivity to the response of the studied metasurfaces.
