We demonstrate the angle, polarization and intensity tunability of the optical Kerr effect in gold/alumina metamaterials investigated by the z-scan technique. We propose a model to predict their effective nonlinear refractive index and absorption coefficient.

Abstract
We demonstrate the angle, polarization and intensity tunability of the optical Kerr effect in gold/alumina metamaterials investigated by the z-scan technique. We propose a model to predict their effective nonlinear refractive index and absorption coefficient.File in questo prodotto:
