Abstract

We have developed the magneto-optic spatial light modulator (MOSLM) with one-dimensional magnetophotonic crystal (1D-MPC). The multilayer structure of SiO₂, Ta₂O₅, and bismuth substituted yttrium iron garnet (Bi:YIG) were deposited by the RF magnetron sputtering to form 1D-MPC. By using 1D-MPCs, The large enhancement in Faraday rotation was obtained in localized light mode, and the fabricated MOSLM showed higher contrast than that of single magnetic film. We confirmed the brightness of the magneto-optical image changed by an external magnetic field.
