    Abstract: We magneto-optically investigate the switching properties of the grooved pixels. The switching field of the 70%-grooved pixel achieves a factor of over two reductions more than that of the 100%-grooved pixel. The switching properties of the geometric pixel arrays for the magneto-optic spatial light modulators are very sensitive to the depth of the pixel groove, and also depend on the state of individual pixel, in additions to the state of the neighbors in two-dimensional pixel arrays. Optimally grooved pixels can allow high amounts of bismuth in the iron garnet film, and actually reduce the driving current of the magneto-optic spatial light modulator due to a low switching threshold field.

    Abstract: Optical properties of cobalt-doped zinc aluminosilicate transparent glass ceramics in the visible – near-infrared (IR) spectral range have been studied. It was shown that the absorption and luminescence properties of these glass ceramics are defined mainly by tetrahedrally coordinated Co2+ ions located in ZnAl2O4 gahnite nanocrystals formed in the glass ceramic matrix. The luminescence in the visible and near IR was assigned to the transitions from the T14(4P) to the A24 and T24 energy levels of tetrahedrally coordinated Co2+ ion. Absorption saturation and bleaching relaxation under excitation of the A24→4T1(4F) transition were studied. Luminescence decay and bleaching relaxation times lie in the ranges 25–200 and 500–800 ns, respectively, depending on the Co concentration. The value of the ground-state absorption cross section of tetrahedrally coordinated Co2+ ions in zinc aluminosilicate transparent glass ceramics was estimated to be 2.0×10−19 cm2 at the wavelength of 1.54 μm.
