An interferometric optical isolator, with a TiO2/magnetic garnet waveguide, employing a nonreciprocal phase shift was studied. The nonreciprocal phase shift in the magneto-optic waveguide was calculated at a wavelength of 1.55 μm. The large nonreciprocal phase shift was obtained when the magneto-optic waveguide had a TiO2/magnetic garnet guiding layer. An optical isolator which could be operated in a unidirectional magnetic field was also discussed.
