Abstract

A theory of light propagation through one-dimensional photonic crystals and deterministic aperiodic structures, including quasicrystals, based on doped quantum-well structures has been developed. The resonant Bragg condition, leading to the superradiant regime and formation of the widest optical reflection spectrum, has been formulated. The expressions for band gap edges for light waves in the Bragg structures have been obtained. The reflection and absorption spectra of such systems are calculated. The optical properties of the doped multiple-quantum-well structure are compared with the properties of undoped ones.
