Abstract
We experimentally demonstrate the capability of semiconductor monolithic metasurfaces to control the polarization state of optical second-harmonic generation. Based on the properties of single Mie-resonator scattering, we design and fabricate AlGaAs-on-insulator metasurfaces whose spatial periodicity allows us to decouple polarization and diffraction features. This enables collection of a polarization-engineered harmonic field in a small solid angle around the zero-diffraction order. Our metasurfaces rely on a AlGaAs/AlAs/GaAs metal-organic chemical vapor deposition structure, which makes them promising for optoelectronic integration.
