The isolation effect was studied in a Cd_1−xMn_xTe magneto-optical waveguide grown on a GaAs substrate. By use of prism coupling, an isolation ratio of 20 dB was achieved at lambda = 740 nm under a magnetic field of 5 kG. The high isolation ratio obtained in the magneto-optical waveguide grown on the semiconductor substrate shows the feasibility of monolithical integration of an optical isolator with semiconductor optoelectronic devices.
