| Abstract(in English) | An optical isolator plays an essential role in protecting optical devices from unwanted reflection. Commercially available optical isolators based on the Faraday effect, which are provided with optical fiber or beam interfaces, are hard to be integrated with other optical devices. In case of waveguide isolators, it is quite harad to make use of a polarization rotation, because the precise control of waveguide birefringence is needed. Sevevral approaches, like a nonreciprocal radiation and a monreciprocal loss isolator, have been developed to circumvent this problem. An interferometric waveguide isolator, which uses a nonreciprocal phase shift provided by the first-order magneto-optic effect, has the advantages of a single polarization operation and a wide operational wavelength range. Also, the isolator is realizable in several waveguide platforms by directly bonding a magneto-optic meterial as a cladding layer. The integration fo optical isolators will be addressed in this article. |
