摘要：
Complete magneto-optical mode conversion was obtained in a 500 nm-thick graded-refractive-index Cd1-xMnxTe waveguide grown on GaAs substrate. For the annealed waveguide, significant improvement of the complete mode conversion ratio was achieved up to 35 nm operational wavelength range. The Cd1-xMnxTe waveguide also showed very low optical loss of 0.2 dB/cm, high magneto-optical figure-of-merit of more than 1000 deg/dB/kG and isolation ratio of more than 20 dB. This result is an important step toward acheiving a practical integrated optical isolator. (c) 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
