Photonic Crystals with Tunable Band Gap Based on Infilled and Inverted Opal-Silicon Composites

Abstract

Three-dimensional opal-Si composites with both direct (a variable extent of filling of opal voids with Si) and inverted structures have been synthesized. A structural analysis of these fabricated systems is performed. Reflectance spectra from the surface (III) of the composites are measured. Observed spectral features are interpreted as a manifestation of the direction III photonic band gap that is tunable in position and width in the visible and near-infrared spectral ranges.
