Resumen
We present three different methods for the modeling of disorder effects in three-dimensional photonic crystals. In order to reproduce experimental results, we apply a method based on a statistical distribution of sphere sizes and vacancy density in a colloidal crystal slab. The other two methods consist of adding extinction to the theoretical model so energy losses account for the diffuse light scattering produced by imperfections in the crystalline structure, which removes energy from coherently scattered waves. Although we exemplify the case of synthetic opals, our analysis also applies to other kinds of photonic crystals. © 2009 The American Physical Society.
