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

We experimentally demonstrate simultaneous generation of second-, third-, fourthharmonic, sum-frequency, four-wave mixing and six-wave mixing processes in III-V semiconductor metasurfaces and show how to tailor second harmonic generation to zerodiffraction order via crystal orientation.
