| Outline of Final Research Achievements |
Isolators employing cladding layers of magneto-optic garnet films on silicon waveguides are very attractive for realizing optical integrated circuits. We investigate a waveguide optical isolator using a Mach-Zehnder interferometer (MZI) with an upper cladding layer of a magneto-optic garnet film crystalized by using the contact epitaxial method which consists of contacting a seed crystal and heating the film process. As an elemental study, the evaluation method of propagation loss in a silicon waveguide loaded with an upper cladding layer of cerium substitution yttrium iron Garnett (Ce:YIG) film in an asymmetric MZI waveguide was proposed. After the contact epitaxial process, the reduction of the propagation loss in in silicon rib waveguides having the Ce:YIG upper cladding layer was obtained. High crystallinity and developing magneto-optical effect were also demonstrated with Ce:YIG films formed on the silicon layer by using the contact epitaxial technology.
