• Graded-index clad layers with different thickness were used to increase the magneto-optical TE-TM mode conversion efficiency in Cd_<1-x>Mn_xTe waveguide. Almost complete mode conversion efficiency of 98% ± 2% was achieved for the waveguide with 4000-5000 Å thick graded layer at λ = 7 40 nm and H = 5.5 kG. The high mode conversion efficiency is due to the strong reduction of the phase mismatch between TE and TM modes. The waveguide also showed low optical loss below 1 dB/cm, high magneto-optical figure-of-merit above 500 deg/dB/kG and an isolation ratio of 18 dB at λ = 740 nm. Highly efficient present Cd_<1-x>Mn_xTe waveguide demonstrates the feasibility of monolithical integration of an optical isolator with semiconductor optoelectronic devices.
