An optical isolator with a Si guiding layer that makes use of a nonreciprocal phase shift is discussed. The Si guiding layer is sputter-deposited on a garnet substrate. The magnetooptic waveguide in the optical isolator has an air/Si/magnetic-garnet structure. The optical isolator can be operated in a unidirectional magnetic field owing to an interferometer with distinct layer structures. Various layer structures will be proposed for unidirectional magnetic field operation.
