Abstract

We discuss the experimental data on laser diffraction in photonic crystal films with an inverse opal structure. Two types of samples based on tungsten and manganese oxides were prepared by replicating colloidal crystals of 900 nm polystyrene microspheres. We scanned both colloidal crystals and inverse opals with a 532 nm laser beam and recorded symmetrical sixfold diffraction patterns for all samples studied. By using laser diffraction it is possible to calculate the period of photonic crystals and to examine their crystalline quality. This method allows monitoring evolution of the samples from colloidal crystals to inverse opals in a replicating process.
