Numerical Simulation of Optical Properties of Photonic Crystals with Inverse Opal Structure

— Optical characteristics (photonic band gaps (PBGs)) of inverted photonic crystals (PCs) of ethoxylate trimethylolpropane triacrylate (ETPTA) are theoretically analyzed; calculated characteristics are compared with experimental data. Band structures of inverted PCs in the [111] direction for samples with various photonic stop band positions are determined. It is found that theoretical calculations are in good agreement with the data on reflectance spectra.
