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

Abstract

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.
