Abstract :
We have subsequently developed planar photonic crystals (PPCs) specifically for nonlinear optical conversion studies. In particular we designed and realized a square-lattice PPC that has bands that exhibit almost no dispersion along the entire Γ-X direction of the square Brillouin zone. These flat bands offer tuning flexibility and conversion efficiency advantages when considering PPCs as hosts for 2 nd harmonic generation. We have recently extended our self-consistent scattering model to include 2 nd order polarization terms. This allows us to estimate the absolute external second harmonic generation efficiency in specular reflection when exciting the PPC from the top half space
