In the present study, we present a new type of an integrated magnetooptical isolator. We considered the film and the cover regions are magnetooptic while the substrate is made of metamaterial. The proposed isolator uses only the TM mode propagating perpendicular to the in-plane magnetization of a planer magnetooptical waveguide. The cut-off thickness of the integrated isolator varies with the propagation direction. The chosen thickness of the proposed isolator yields a big difference between the...
