Influence of the size-dependent permittivity of metal inclusions on the optical characteristics of a one-dimensional photonic crystal with a nanocomposite defect
The spectral characteristics of a one-dimensional photonic crystal structure with a defect nanocomposite layer that consists of metallic nanoparticles distributed in a transparent matrix are theoretically studied. The defect mode shape inside the photonic band gap is found to depend substantially on the nanoparticle size and concentration in the defect layer.
