In this paper the magneto-optical responses of single-cavity and dual-cavity type onedimensional 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.
