- 論文の詳細を見る
We have fabricated optical waveguides using amorphous Bi3Fe5O12 (BIG) film deposited by RF magnetron sputtering at room temperature and evaluated the Faraday effect. The fabricated waveguide consists of Si waveguides and a short BIG waveguide. Light propagation loss of the BIG waveguide is 100 dB/cm. The optical modulation of 9% was obtained on the basis of the Faraday effect using the BIG waveguide/polarizer system at an external magnetic field of 2000 Oe. The figure of merit of 10 deg/dB, which is 1/4 that of an epitaxial BIG film, was obtained.
