Amplification of electromagnetic radiation from 3D photonic crystals with quantum-dot gain material inclusions

In this paper the scattering characteristics are calculated with the technique based on the volume integral equations for polarization currents. A study of electromagnetic field interaction with the 3D lattice dielectric structure involved defect layer and gain material is performed in this paper. An effect of gain material parameters on the amplification level of the structure is investigated. Distributions of the internal electric field intensity over the periodic cell are presented.
