摘要： An adapter 5 for an optical connector comprises a pair of wall portions 55a and 55b on a mounting surface 56a. The structure allows the adapter to accommodate an optical connector 4 inserted from a direction vertical to the mounting surface 56a, and allows the adapter to accommodate an optical connector 7 inserted along a predetermined axis 8. On this account, it is possible to insert the connector 7 along the predetermined axis 8 to the housed optical connector 4. Since the optical connector 4 is mated to and demated from the optical connector 7 in this sort of adapters, force applied to an optical module 2 is decreased in mating/demating the connector. An optical module product 9 includes the optical module 2, a coated optical fiber 3, the optical connector 4, and the optical connector's adapter 5. An optical module mounting substrate product 1 includes the optical module product 9 and a substrate 10 for mounting thereon the optical module 2 and the adapter 5 for optical connectors.

摘要： To provide a reliable optical pickup device, a pickup case and an optical component including a lens are fixed by laser welding to increase the welding strength and reduce the positional displacement due to environmental changes. In a laser welded portion between a pickup case and an optical component including a lens, the optical component is provided with a joint portion having a convex protrusion at a portion to be joined to the pickup case. Laser beam irradiation is performed extending longer than the protrusion to form a thick welded portion at an end of the protrusion, in order to increase welding strength between the optical component and the pickup case.

摘要： In an optical pickup device, a side surface parallel in the optical axis direction of an optical component is respectively fixed with an adhesive at wall surfaces (internal walls) provided opposing with each other of an accommodation case. In a part of the wall surfaces of the accommodation case, a recessed channel to be filled with the adhesive is formed. The recessed channel is provided with a stepped portion along the optical axis of the optical component at the wall surfaces of the accommodation case. A gap between the relevant side surfaces and the side surface of the optical component is formed to be reduced symmetrically toward both end portions from the center in the optical axis direction of the optical component. Accordingly, bonding strength is never lowered and position of the optical pickup device is stably maintained in an optical system.

摘要： In anodic bonding between a conductor or semiconductor and glass, in order to attain good adhesion at a lower bonding temperature than usual and improve the toughness at its boundary to obtain higher reliability for a bonded portion even in a case where bonded members are warped or dust is present at the bonding boundary, a soft metal film is formed on the surface of a conductor or semiconductor on which an active metal film having high reactivity with oxygen is formed, whereby a warp or dust, if any, can be absorbed by the deformation of the soft metal film, thereby to improve the adhesion at the boundary. Adhesion at the bonding boundary is improved even at a low bonding temperature of, e.g., about 200° C. Further, the toughness at the bonding boundary can be improved to increase reliability by roughening the bonded surface on the side of the glass.

摘要： A PD (20) is mounted to a position offset (23) as viewed in the direction orthogonal to the center of an optical axis (14) of backward light (13) of an LD (11) in such a manner that a light receiving plane (21) thereof becomes substantially parallel to the center of the optical axis. Alternatively, the PD (20) is mounted thereto so that the light receiving plane of the PD is inclined at angles ranging from about 0° to about 30° to the center of the optical axis of the backward light. Further, the PD whose side face on the LD side is inclined, is used to repeatedly reflect the backward light between the PD and an LD mounting substrate, after which the backward light is launched on the light receiving plane 21. An optical module equipped with a PD for monitoring optical output power of an LD can be applied even to a junction up LD which reduces the number of parts, reduces even the number of connections by solder or the like and the number of electrical connections by wire bonding or the like, and makes no use of a base for the PD. Thus, low-cost PD mounting can be realized.
摘要翻译：从与LD（11）的反光（13）的光轴（14）的中心正交的方向观察，PD（20）被安装到位置偏移（23），使得光接收平面（21）变得基本上平行于光轴的中心。或者，PD（20）安装在其上，使得PD的光接收平面相对于向后光的光轴的中心约0°至约30°的角度倾斜。此外，LD侧的侧面倾斜的PD用于反复反射PD与LD安装基板之间的反光，然后在光接收面21上发射反光。具有用于监视LD的光输出功率的PD可以甚至应用于结合上LD，其减少部件的数量，甚至通过焊料等减少连接的数量以及通过引线接合等的电连接的数量，并且不使用PD的基础。因此，可以实现低成本的PD安装。

摘要： To provide an optical pickup device adapted such that for adhesion fixing of a holder for holding an LD or a light-receiving element to an optical pickup casing via an ultraviolet-curable adhesive, curing shrinkage during ultraviolet irradiation can be reduced and adhesion fixing achieved with high positioning accuracy. In a structure for adhesion fixing of a holder for holding an LD or a light-receiving element to an optical pickup casing via an ultraviolet-curable adhesive, since protrusions are provided at peripheral sections (UV irradiation light source side) on a bonding surface of the holder, a section exposed to strong UV light is first cured, then after the adhesive has moved from an uncured section, the amount of shrinkage of the first cured section in a Z-direction is reduced, and the uncured section is cured.
