A second-harmonic superprism effect in 2D photonic crystals is demonstrated numerically. A full control of the second-harmonic emission is achieved by tailoring the photonic dispersion curves. This effect is demonstrated by using a multiple scattering method generalized to the second-harmonic generation. We show that small angular variations or a wavelength tuning of the fundamental field induce large shifts of the second-harmonic emission (∼90°).
