摘要： A nonlinear Y-junction waveguide structure includes a straight linear waveguide, and a nonlinear waveguide partially joined to the linear waveguide and bent through a desired angle at an output end portion thereof, whereby incident light coming into the linear waveguide travels mainly along the linear waveguide when it has a power lower than a predetermined level while traveling mainly along the nonlinear waveguide when it has a power not lower than the predetermined level. The nonlinear Y-junction waveguide structure has an increased branching angle as compared to the conventional completely-operating optical device and exhibits an abrupt switching phenomenon. Accordingly, it is possible to achieve an easy adjustment of the critical power. In this regard, there is no difficulty in the fabrication of the waveguide structure.

摘要： The present invention relates to a manufacturing method of a polymer GRIN lens which is used for focusing light in connections for example between two or more optical fibers and between an optical fiber and a light source in the optical communication field. The manufacturing method of a GRIN lens according to the present invention utilizes a characteristic of polystyrene that its refractive-index is decreased by sulfonation. The method includes polymerizing a sphere or rod made of a directional monomer that is capable of sulfonating like a styrene, together with a cross-linking agent, and a polymerization initiator; swelling the polymerized cross-linked polymer by using a predetermined solvent; and sulfonating the swollen cross-linked polymer using a sulfuric acid. Accordingly, the present method can be easily controlled to obtain the desired refractive-index distribution since the refractive-index distribution is determined by the diffusion of the sulfuric acid as a sulfonation.

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.
