ABSTRACTAn optical isolator with a TiO2/(CeY)3Fe5O12 guiding layer was studied. A nonreciprocal phase shift was calculated in the magneto-optic waveguide with the TiO2/(CeY)3Fe5O12 guiding layer at a wavelength of 1.55 μm. By employing a multimode interference coupler as coupling devices, the total device length of approximately 600 μm was achieved. An interferometric optical isolator with distinct layer structures, which could be operated in a unidirectional magnetic field, was also designed.

AbstractA novel configuration of an integrated optical isolator employing a nonreciprocal phase shift is proposed. The isolator is equipped with a cladding layer of magnetic garnets by means of wafer direct bonding technique. This device has a semiconductor guiding layer, so high compatibility in integrating with other semiconductor optical devices is expected.
