Description
Summary:The 1-D magnetophotonic crystals having a structure of (AB)kM(BA)k, where k is the number of stacking layer, M is Bi-substituted iron garnet with a Bi content of 0.5 and 1.07, and A and B are SiO2 and Ta2O5, resp., were numerically simulated in the visible and near ir wavelengths. The Faraday rotation angle, transmittance, and figure of merit of the 1-D magneto-photonic crystals (1D-MPCs) as a function of Bi content and the thickness of the magnetic garnet layer are presented. In the near ir region, several hundred times larger Faraday rotation angle reaching 30-40 degrees and several ten times of figure of merit reaching 0.4-0.5 were obtained as compared to the garnet single layer. In particular, the figure of merit of the 1-D magnetophotonic crystals in the near ir region was several times larger than that in the visible region. 3 refs.
