Abstract

Abstract

Matured syntheses of inorganic nanocolloids today have allowed production of diverse asymmertic nanoparticles (NP) and even more complex assemblies, introducing a variety of nanomaterials with unique properties. Chirality is one of most intriguing symmetry groups in field of material science due to the optical rotatory power of chiral substances.

Abstract

Abstract

We show that via engineering inhomogeneous electron temperature distribution in hybrid plasmonic nanoparticles and self-assembled metamaterials, accelerated or delayed nonlinear optical response can be designed with the enhanced Kerr-type nonlinearity. Combined with anisotropic properties of metamaterials, nonlinearity leads to efficient all-optical control of light polarisation.

Abstract

Abstract

We introduce a powerful homogenization-method to calculate effective nonlinear susceptibilities of metasurfaces and use it to demonstrate that the second-order susceptibility of graphene metasurfaces and Raman susceptibility of metasurfaces made of silicon photonic crystal cavities can be enhanced by more than two orders of magnitude.
