    摘要: A waveguide type optical component, as an optical coupler/splitter, is provided, which is capable of reducing the dependence of the efficiency of optical coupling between optical waveguides on wavelength and of permitting reduction in size. The optical component has a first optical coupling section (A) including optical waveguides (A1, A2) sharing the same propagation constant, a second optical coupling section (B) including optical waveguides (B1, B2) having different propagation constants, and a third optical coupling section (A') including optical waveguides (A'1, A'2) sharing the same propagation constant. Associated ones of the optical waveguides (A1, B1, A'1; A2, B2, A'2) are connected in series with each other.

    摘要: This invention describes a method of manufacturing silica waveguide optical components in which silica glass films are laminated on a substrate by repeating a unit operation in which a sol material, a precursor of glass particles, is coated and then the coated layer is heated in an oxygen atmosphere. wherein the heating temperature is controlled in such a manner that the radius of curvature of warping of the substrate is 2 m or more after the coated layer is heated, thereby preventing cracking in the formed silica glass film and/or peeling of the coated layer. At locations where a difference in height is present, at least when sol is coated first time, the thickness of the coated layer is less than that of one of the subsequent coated layers.

    摘要: A method for manufacturing waveguide-type optical components featuring a lower propagation loss at low cost in which a lower clad section (2) made of silica glass is formed on a substrate (1), and an antistatic layer and a mask layer having a desired pattern are formed on the surface of the lower clad section (2) in the order they are listed. Then, an electron beam is irradiated from above the mask layer to produce a core (6) of the desired pattern in the lower clad section (2), the mask layer and the antistatic layer are removed to expose the surface of the lower clad section (2), and an upper clad section (7) having a lower refractive index than the core (6) is formed on the exposed surface of the lower clad section (2), thus producing an optical component. The surface of the whole optical component is at a distance from the core; therefore, the scattering loss caused by minute irregularities on the surface of the optical component is reduced.

    摘要: An optical switch includes at least one input optical semi-conductor waveguide. Two output optical semiconductor waveguides are connected at a branch point to the input optical waveguide, and diverge from the branch point with a preset angle .theta. (degree) between them. A refractive index controlling portion is located on at least one of the output optical waveguides and away from the branch point. The refractive index controlling portion effects a light mode cut-off by electromagnetically causing a reduction of the refractive index of the associated output optical waveguide.

    摘要: A method of connecting an optical fiber to a planar optical waveguide is provided in which an end face of a waveguide chip in which planar optical waveguides are formed is abutted against an end face of a fiber aligning jig on which optical fibers are arranged, to thereby connect the optical fiber to the corresponding planar optical waveguide. At least one marker is formed in each of the waveguide chip and the fiber aligning jig, and also at least one pin guide groove is formed in each of the waveguide chip and the fiber aligning jig, using the marker as a reference mark. The markers of the waveguide chip and the fiber aligning jig are aligned with each other along optical axes of the planar optical waveguides when the waveguide chip and the fiber aligning jig are abutted against each other. Further, fiber guide grooves are formed in the fiber aligning jig, using the marker as a reference mark. The waveguide chip and the fiber aligning jig are abutted against each other, and the planar optical waveguide and the optical fiber are aligned with each other by means of a common guide pin laid along the corresponding pin guide grooves.
