A finite difference method in real space is presented for calculating nonlinear optical processes in two-dimensional optical superlattices. The focused second-harmonic generation under the local quasi-phase-matched condition is calculated as an example. The field distribution of both the fundamental and the harmonic wave can be simulated well using this method, and the result agrees well with previous theoretical predictions and experimental studies. It is shown that this method is a simple and rapid technique to analysis nonlinear processes in optical superlattices.
