Abstract :
A concept for an integrated optical Mach-Zehnder interferometer isolator for TE modes is presented. Vertically magnetised magneto-optic rib waveguides with a compensation wall serve as nonreciprocal phase shifters for the fundamental TE mode. The nonreciprocal phase shifts in both interferometer arms add as the jumps of the Faraday rotation at the compensation walls have opposite sign
