In this paper, a proposal for designing the one-dimensional magnetophotonic crystals operating at visible wavelengths is presented. To this aim, a binary all-dielectric periodic structure is considered with quarter wavelength optical thicknesses condition. However, the Bi:YIG as a magneto-optical defect layer with two different optical thicknesses of λ0/ 2 and 4λ0 is utilized. Using the 4 × 4 transfer matrix method the defect mode properties of the considered structures are investigated regarding the different period numbers and various magneto-optical defect layer positions. Analyzing the transmittance, Faraday rotation and absorption coefficient of these structures for the 720 nm visible light, the optimum structures are proposed for both cases of magneto-optical defect layer thicknesses. These structures may have potential applications in designing the miniaturized magneto-optical devices such as magneto-optical sensors and isolators and integrated photonic elements.
