Paper Abstract

We manipulate the second harmonic generation (SHG) near-field and far-field radiation properties from metasurfaces composed of split ring resonators (SRRs). The manipulation is done by inverting the symmetry of the SRRs in periodic manner. We show by numerical models and experimentally that by that the nonlinear emission can be directed and that the emission direction can be controlled by changing the properties of the arrays or by changing the wavelength of the exciting beam at the first harmonic. This can be used as a new form of all-optical nonlinear scanner based on extremely thin metasurface. These methods open the door for development of new integrated nonlinear active devices based on metasurfaces and can be used to enhance the efficiency of the nonlinear output, therefore it provides a major step forward towards the development of efficient nonlinear metamaterials.
