We present a model for second-harmonic generation in a two-dimensional array of quantum dots. We show that the combined effect of the electromagnetic local field of the array and the intrinsic electronic resonances that arise from spatial confinement in the quantum dot produces great enhancements of the second-order nonlinear susceptibilities, hence giving a high efficiency of second-harmonic generation.
