  • Abstract
    Demonstrates the tuning of linear birefringence in magneto-optic planar thin-film waveguides by temperature adjustment. Using this method, phase matching between coupled TE0 and TM0 modes, a necessary condition for the integrated optical isolator based on mode conversion, has been obtained at lambda =1.52 mu m in bilayer gadolinium gallium-substituted YIG films. The waveguide temperature was 85 degrees C. Moreover, the phase-matching temperature can be modified by a slight variation of gadolinium and gallium substitutions as shown by a phase matching observed in a waveguide at room temperature.
