Inorder to fabricate the device for monolithic integration, the wafer direct bonding between a magnetic garnet material as a cladding layer and a semiconductor guiding layer has been achieved. We found that wafer direct bonding between InP and GGG (Gd3Ga5O12) is effective for the integration of a waveguide optical isolator. The isolation ratio was obtained to be 2.9 dB in the device. 한국자기학회 A Magneto-Optic Waveguide Isolator Using Multimode Interference Effect Article 2 Journal of Magnetics, v.10, no.2, pp.41 - 43 Journal of Magnetics 10 2 41 43 kci ART000964658 optical isolator multimode interference nonreciprocal phase shift wafer bonding optical isolator multimode interference nonreciprocal phase shift wafer bonding
