We report highly-nonlinear ultrathin metasurfaces based on coupling of plasmonic nanoresonators with intersubband nonlinearities. Nonlinear susceptibilities over 1×106 pm/V and conversion efficiencies ∼0.1% were measured for second harmonic generation in mid-infrared for 10 kW/cm2 input intensity. Complete phase control of local nonlinear response is demonstrated.
