Metamaterials comprising assemblies of dielectric resonators have attracted much attention due to their low intrinsic loss and isotropic optical response. In particular, metasurfaces made from silicon dielectric resonators have shown desirable behaviors such as efficient nonlinear optical conversion, spectral filtering and advanced wave-front engineering. To further explore the potential of dielectric metamaterials, we present all-dielectric metamaterials fabricated from epitaxially grown III-V…

Forward and Backward Switching of Nonlinear Unidirectional Emission from GaAs Nanoantennas.
The technique provides an approach not only for unidirectional second-harmonic generation (SHG) forward or backward emission, but also for switching from one to another, and switching the SHG emission directionality is obtained only by rotating the polarization of the incident light, without the need for physical variation to the antennas, or the environment.
