title: Controllable polarization coupled dual-focused second-harmonic generations in a two-dimensional optical superlattice.
abstract: The nonlinear Huygens-Fresnel principle has been used to design multifunctional nonlinear optical devices. Focused second-harmonic generations have been observed with strong polarization sensitivity. Numerical simulations have been performed, and the results fit well with the experiments.
