Efficient second harmonic generation from GaAs all-dielectric metasurfaces

Liu, Sheng L.; Keeler, Gordon A.; Reno, J.L.; Yang, Yuanmu Y.; Sinclair, Michael B.; Brener, Igal B.

We experimentally observe large enhancement of second-harmonic generation (SHG) from GaAs metasurfaces. The SHG polarization when excited at the electric and magnetic dipole resonances is orthogonal and can be attributed to different nonlinear generation mechanisms.
