摘要:
To obtain an optical waveguide device capable of improving mounting accuracy and productivity for correcting misalignment of alignment marker caused by distortion due to a substrate stressed and distorted. An optical waveguide device includes an optical waveguide section, including a waveguide core formed on a substrate, and an optical device (LD) mounted on the substrate to correspond the optical waveguide section, both of which are coupled at a light end face and mounted by hybrid mounting. LD side alignment markers are provided in both sides of an active line in the optical device. Substrate side alignment markers are provided at positions where centers thereof and those of the optical device side markers are matched when the optical device is mounted on the corresponding substrate. Fiducial markers are provided and a relative positional relationship with the waveguide core on the substrate becomes stably. Thus, a misalignment amount is detected.

An LSI package having an optical interface is mounted on a surface of a photoelectric wiring board. The photoelectric wiring board and the optical interface are optically connected with sufficient precision. A wiring board side guide member including socket pins and guide pins is soldered and fixed onto the photoelectric wiring board including an optical transmission line, a guide pin, and a mirror. An optical interface side guide member having a fitting hole is glued to the optical interface. The optical interface is mounted on an interposer of the LSI package. The guide pin of the photoelectric wiring board is fitted into the fitting hole formed through the interposer. The guide pin of the guide member is fitted into the fitting hole of the guide member. As a result, position alignment between the optical interface and the photoelectric wiring board is conducted with high precision.

An optical waveguide module includes a wiring board, and a light-receiving element and optical waveguide substrate that are positioned on both sides of this wiring board. The wiring board includes a base member having transparency to light of the wavelength that can be received by the light-receiving element; surface electrical wiring on the surface of the base member, and filter film on the rear surface of the base member for passing only light of the wavelength that can be received by the light-receiving element and for reflecting light of other wavelengths. An aperture larger than the core of the optical waveguide is formed in the surface electrical wiring. The light-receiving element (9) is flip-chip mounted on surface electrical wiring (4) using bumps (11), and the light-receiving region (10) of the light-receiving element (9) is arranged to face the wiring board (7).

A light receiving element (12) is mounted on a wiring board (9) with a first opening (10) formed on the wiring board (9) being aligned with a light receiving region (13). Two second openings (11) formed in the same process as used for the first opening (10) are provided on the wiring board (9). An optical waveguide having a core (3) of the optical waveguide, and two board marks having cores (5) of dummy optical waveguides are provided on an optical wiring board. At the time of optically coupling the light receiving region (13) and the core (3) of the optical waveguide, the openings (11) and the board marks are observed from the side of the light receiving element (12) on the wiring board (9) at the same time, and the wiring board (9) and the optical wiring board are aligned with each other based on the positions of the observed openings and board marks. This can ensure easy and highly accurate mounting assembly, and improve mass productivity.

A stick-type cosmetic container including an outer cylinder, a sleeve, an inner container in which a stick-type cosmetic can be filled, one or more small projections provided on the inner container being guided by an inner container guiding groove formed on the sleeve, the small projection moving upward and downward along a helical groove formed on the inner surface of the outer cylinder, and the stick-type cosmetic filled in the inner container being projected and retracted. The lower end of the inner container guiding groove formed on the sleeve is opened and a retaining mechanism for the small projection is provided at the lower portion of the inner container guiding groove. Refilling and replacement of the stick-type cosmetic container can be performed by the use of a simple jig, and there is no problem of dropping of the inner container when in use.

摘要:
A method for connecting an optical waveguide and an optical semiconductor device and an apparatus for connecting the same, capable of removing a working error and getting a high optical coupling coefficiency. The method consisting of the steps of: moving the optical semiconductor device to the substrate so as to overlap the pair of the first positioning marks and the pair of the second positioning marks; obtaining an actual distance from the outgoing surface to the pair of the second positioning marks, based on an image photographed by allowing the infrared ray to transmit through the substrate and the optical semiconductor device; obtaining an error between the actual distance and a designed distance previously set, by subtracting the designed distance between the outgoing surface of the optical semiconductor device and the pair of the second positioning marks from the actual distance; moving the pair of the second positioning marks relative to the pair of the first positioning marks by a quantity equal to the error so as to cancel the error; and jointing the optical semiconductor device to the substrate.
