Abstract

We demonstrate wavefront shaping of third-harmonic light generated in nonlocal silicon metasurfaces. The nonlinear geometric phase principle is applied to locally control the phase response of the diffracted third-harmonic light. The use of nonlocal modes entails the possibility to operate with high Q-factor modes, thus improving the conversion efficiency. Unlike the linear process, we find that the designed metasurfaces can convert circularly polarized light to linearly polarized light. Our results are promising for the development of a new approach to nonlinear wavefront shaping metasurfaces.
