Abstract :
Reduction of optical absorption as the amount of Bi in Bi-substituted films is increased is discussed. The amount of Bi in the films grown was controlled by adjusting the supercooling temperature of the solvent, the ratio of PbO to Bi2O3 in the solvent, the substrate rotation speed and other parameters. Variation in Bi content with respect to Bi-YIG was found at substrate rotation speeds of 84 rpm and 170 rpm. The measurements of the absorption characteristics of Bi-GdIG and Bi-GdGaIG films grown on a GGG substrate indicated that they included a Bi quantity of approximately 0.8 with respect to the Bi-GdIG. A figure of merit of 6.7 deg/dB was obtained for a 21.2 μm thick Bi-GdIG film at a wavelength of 0.76 μm.
