    "abstract": "By numerically integrating the three-dimensional Maxwell equations in the\ntime domain with reference to a dispersive quadratically nonlinear material, we\nstudy second harmonic generation in planar photonic crystal microresonators.\nThe proposed scheme allows efficient coupling of the pump radiation to the\ndefect resonant mode. The out-coupled generated second harmonic is maximized by\nimpedance matching the photonic crystal cavity to the output waveguide.",
