摘要： Disclosed is an optical waveguide element wherein a plurality of Mach-Zehnder waveguides to be used for DQPSK modulation and the like are integrated on a thin substrate and the on/off extinction ratio is improved. The optical waveguide element has the thin board, which is formed of a material having electrooptical effects and has a thickness of 20 μm or less, and an optical waveguide formed on the front surface or the rear surface of the thin board. The optical waveguide has the plurality of Mach-Zehnder waveguide sections, and multiplexes optical waves outputted from two or more Mach-Zehnder waveguide sections. In the multiplexing section in each Mach-Zehnder waveguide section (MZA), a triply branched waveguide, which is composed of a waveguide for output (c1) and two waveguides for radiation (b1, b2) disposed to sandwich the waveguide for output, is formed. High-order mode light absorption regions (d1, d2) are formed between the waveguide for output and the waveguides for radiation in the triply branched waveguide.

摘要： To provide an optical device sealing structure capable of simply sealing an optical fiber inserting portion. Provided is a structure that seals an optical device including a metallic case having an optical element disposed therein and an optical fiber inserted through a through hole of the case, wherein a Zn-containing surface is formed on a surface of a bare fiber portion that is formed by partly removing a coating of the optical fiber so as to expose a bare fiber, and wherein an Sn-containing sealing material is charged between the Zn-containing surface and an inner wall of the through hole.

摘要： The waveguide-type polarizer includes: a Z-cut lithium niobate substrate; an optical waveguide having a ridge structure and formed on the substrate; a low refractive index film formed with a thickness satisfying 0≦n·t/λ≦0.3742 (where n is a refractive index, t (μm) is the thickness of the film, and λ (μm) is the wavelength of a light wave) on the side of the ridge structure; and a high refractive index film formed with a thickness satisfying 0.089≦n·/λ on the low refractive index film. The width of the ridge structure is a ridge width where the distribution of ordinary light of the light waves propagated through the optical waveguide changes and the distribution of extraordinary light of the light waves does not change, the angle of the ridge structure is less than 90°, and the waveguide-type polarizer has a function of transmitting extraordinary light.
