    Abstract: An optical waveguide device includes: a substrate having an electro-optical effect; an optical waveguide section formed on the substrate; and a plurality of modulating electrodes for modulating optical waves propagating in the optical waveguide section. The optical waveguide section branches into two parts in the propagating direction of the optical waves, thus forming the two main optical waveguides, and each of the main optical waveguides branches into two parts in the propagating direction of the optical waves, thus forming the two sub optical waveguides. The two main optical waveguides constitute a main Mach-Zehnder type optical waveguide, and the two sub optical waveguides are incorporated into the main Mach-Zehnder type optical waveguide to constitute a sub Mach-Zehnder type optical waveguide. A heat conduction suppressing zone is defined on a portion of the substrate disposed between two opposite sub Mach-Zehnder type optical waveguides.

    Abstract: An optical modulation element in which re-incidence of stray light propagating on an adhesive layer to a thin plate is controlled and bonding strength between the thin plate and a reinforcing plate is enhanced. The optical modulation element includes a thin plate (1) formed of a material exhibiting electrooptic effect and having a thickness of 20 μm or less, an optical waveguide (2) formed on the front side or the back side of the thin plate, and a modulation electrode (3) formed on the surface of the thin plate and modulating light passing through the optical waveguide. A surface having a reinforcing plate (5) bonded to the thin plate through an adhesive layer (4) and facing the thin plate of the reinforcing plate is formed as a rough surface (10). Preferably, roughness of the rough surface is one tenth or above of the wavelength of stray light propagating through the adhesive layer.

    Abstract: PROBLEM TO BE SOLVED: To provide a light control element which suppresses entry of non-guided light into an optical waveguide and has excellent optical characteristics such as a light modulation characteristic. SOLUTION: The light control element includes a substrate formed of a material having electro-optic effects and the optical waveguide formed on the front plane or the rear plane of the substrate, wherein propagation constants β 0 -β 3 of the optical waveguide are partly set at different values. Preferably, the light control element is characterized in that the propagation constants of the optical waveguide are different from those relating to the non-guided light which propagates outside the optical waveguide.
