Abstract

In this paper the magneto-optical responses of single-cavity and dual-cavity type one-dimensional magnetophotonic crystals have been investigated considering the constituent layers optical dispersion in near infrared region. The 4 × 4 transfer matrix method has been utilized for calculations and analysis. The obtained results revealed that the resonance transmittance mode is split into two separated modes for specific repetition numbers. These modes are shifted toward the center of photonic band gap regarding the stronger dispersion relations, in both single- and dual-cavity structures. But the amounts of the shifts and their fine behavior are strongly dependent on the type of the structure. We believe that the results of the present work would be practically helpful to precisely design the miniaturized magneto-optical elements in micro- and nano-scale.
