Tailoring second harmonic diffraction in GaAs metasurfaces via crystal orientation

Vabishchevich, Polina V.; Vaskin, A.; Addamane, S.; Liu, S.; Sharma, A.P.; Balakrishnan, G.; Reno, J.L.; Keeler, G.A.; Sinclair, Michael B.; Staude, I.; Brener, Igal B.

We use GaAs metasurfaces with (111) crystal orientation to channel the second harmonic generation (SHG) into the zero-diffraction order that is suppressed for SHG obtained from GaAs metasurfaces with (100) orientation.
