Transmission Spectra of a Symmetric Photonic Crystal Structure with a High-Permittivity Interstitial Layer

Abstract

Transmission spectra are recorded for a one-dimensional photonic crystal structure with the permittivity of the interstitial (or cavity) layer exceeding the permittivity of layers in Bragg mirrors by many times. It is shown that the transmission can be suppressed almost completely both in the photonic band gap (except for a narrow defect-mode region) and beyond it. Specific features of the energy density distribution of the wave field over the structure are revealed.
