摘要：

The nonreciprocal phase shift for TE modes in magnetooptic rib waveguides supporting a domain lattice was recently predicted. Using a single magnetic compensation wall in the symmetry axis of the waveguides, the nonreciprocal phase shift can be enhanced by a factor up to 1.8. The nonreciprocal phase shift is calculated by perturbation theory, The electromagnetic fields are determined by a semivectorial finite-element method which properly handles the required field discontinuities.
