A novel configuration of an intergrated optical isolator employing a nonreciprocal phase shift is proposed. The isolator is equipped with a cladding layer of magnetic garnets by means of a wafer-direct bonding technique. Magnetic garnets with a large magneto-optic effect miniaturise the size of the nonreciprocal phase shifter to several hundreds of microns.
