摘要： PROBLEM TO BE SOLVED: To solve the problem that a substrate and an optical device cannot be welded or may slip off by vibration or impact due to a junction part having the area reduced even in the case of successful welding, because the volume of metal of a holding tool melted during laser welding is reduced in the case that ridges of the bottom of the holding tool are chamfered during laser welding and fixing between the substrate and the optical device. SOLUTION: The optical device and the substrate are fixed by laser welding and fixing, and the size of chamfered parts of ridges in welding parts of the optical device holding tool is set to ≤0.3 mm.

摘要： PROBLEM TO BE SOLVED: To improve heat resistance of an optical waveguide module by using an adhesive having a specific glass transition temperature when a common base board is fixed so as to stride over an optical waveguide chip and optical fiber blocks. SOLUTION: An optical waveguide chip 1 and optical fiber blocks 2 and 3 are connected and fixed to each other by an adhesive 5 after the optical axes are made to coincide with each other. A common base board 4 is fixed by an adhesive 6 so as to stride over the optical waveguide chip 1 and the optical fiber blocks 2 and 3. An adhesive with a refractive index adjusted to cores of the optical waveguide chip 1 and the optical fiber blocks 2 and 3 is used as the adhesive 5. An adhesive having a glass transition temperature higher than a glass transition temperature of the adhesive 5 is used as the adhesive 6. When a module is sealed by using a thermally contractible tube, the glass transition temperature of the adhesive 6 is preferably set higher by at least 20 deg.C or more than a contracting temperature of the thermally contractible tube.

摘要： PROBLEM TO BE SOLVED: To provide a mounting method in which degradation due to inserting loss is suppressed when a thermally contracting tube is mounted into an optical waveguide module where at least one optical fiber is connected and fixed to the both sides of an optical waveguide chip such that optical axes of optical fiber blocks alignedly fixed on a substrate are coincident. SOLUTION: When a thermally contracting tube is mounted to improve long term reliability into an optical waveguide module where at least more than one optical fiber is connected and fixed to the both sides of an optical wave guide chip such that optical axis of optical fiber blocks aligneadly fixed on a substrate are coincident, by decreasing the internal temperature of the thermally contracting tube to at least 20 deg.C lower temperature than glass transition temperature of adhesive agent which is used for connection to glass, mounting of the tube does not degrade the inserting loss. Providing at least 300 deg.C of heat within five second during the mounting suppresses degradation of inserting loss due to the tube mounting.
