We have demonstrated the giant enhancement of second‐harmonic generation in a one‐dimensional GaN photonic crystal structure caused by the simultaneous achievement of strong fundamental field confinement and quasi‐phase matching conditions. We have firstly measured the linear dispersive properties of the resonant modes for various azimuthal directions to predict the quasi‐phase matching conditions. The theory based on a rigorous scattering matrix method has provided a good description of the equi‐frequency surfaces. We have then shown that the equi‐frequency surfaces may be used to identify the angular situations for which the quasi‐phase matching conditions can be satisfied. The SHG enhancement achieved due to the double resonance was 5000 times greater than for the unpatterned GaN layer. (© 2003 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
