Abstract: Spectral characteristics of one-dimensional photonic structures formed by a sequential combination of Bragg reflectors and dielectric layers are investigated. The formation of one or more frequency combs of defect modes in the photonic band gap region is shown. The features of optical field distribution over a defect photonic structure make it possible to implement selective amplification of defect modes.

Keywords: defect photonic crystal, defect modes, optical field localization, selective amplification.
