Abstract

Abstract—The features of the transmission spectra of a one-dimensional photonic crystal are studied, in which the dielectric constant of one of the two layers in the structural period is many times greater than the permittivity of the other. The spectra of a finite defect-free structure, an inversion-defect structure, and a symmetric microcavity structure are considered. The authors demonstrate the possibility of controlling the width of the photonic band gap using an electric field, as well as achieving a very narrow spectral line of the defect mode and an ultrahigh degree of radiation localization at the defect.
