Nonlinear photonic crystals formed by two-dimensional periodic poling of the quadratic susceptibility x ͑2͒ can support quasi-phase-matched harmonic generation. The frequency-conversion efficiency depends on the photonic crystal's poling pattern through certain Fourier coefficients of the poling function. A procedure is described for finding those poling patterns that are most efficient for any specific quasi-phase-matched frequencyconversion scheme.
