    摘要: A semiconductor magneto-optical integrated optical isolator is realized with a Mach-Zehnder integrated optical isolator in which a cladding and a guiding layer of light waveguide are composed of magnetic material. Here, it uses nonreciprocal phase shift created when light propagation direction is changed. The fundamental element deriving this nonreciprocal phase shift is the Faraday rotation of magnetic material. Therefore, it is essential to have large Faraday rotation in order to fabricate a short length integrated optical isolator. However, since magnetic material of bulk state does not have large Faraday rotation, there need the length of several mm units for fabricating an isolator. The invention is to realize an integrated optical isolator using magneto-optical crystal in which magneto-optical material and dielectric substance have periodic structure. By the above reasons, magneto-optical crystal becomes to have bigger Faraday rotation than that of bulk state magnetic materials; thereby nonreciprocal phase shift becomes large and a short length integrated optical isolator can be fabricated. Thus, in order to reduce the device length of a Mach-Zehnder optical isolator, magneto-optical crystal having large Faraday rotation is used.
