損失も急激に減り、長距離大容量化への経済性、信頼性
が図られつつある。The progress of optical communication technology has been remarkable, and the transmission mode of an optical fiber has changed from multi-mode to single mode, and along with this, the transmission loss has drastically decreased, and economical efficiency and reliability for increasing the long-distance and large-capacity are being achieved.
しかし、光ファイバを始め光部品は、益々小形化、高性
能化が要求されて来ている。However, optical components such as optical fibers are required to be smaller and have higher performance.
従って、光部品の組立は、部品間の光軸をより高精度に
調整して合わせ、且つ、部材間を密着固定させることが
必要となる。Therefore, in assembling the optical components, it is necessary to adjust the optical axes between the components with higher accuracy and to align them, and to tightly fix the components.
第３図に従来の一例の光部品組立用治具を示す。 FIG. 3 shows a conventional jig for assembling an optical component.
従来の一例として、レーザダイオードの組立用治具につ

３共に均等に加えられ、且つ外周縁を囲んで作用するの
で、部材B12は水平方向にずれることなく、垂直方向の
押圧のみが加えられる。When the position adjustment is completed, the pressing head 4 is pressed again to the predetermined pressing value, and the member A11 and the member B12 are temporarily overlapped and fixed. At this time, since the taper end surface 31 of the pressing claw 3 presses, the horizontal component force toward the center and the vertical pressing force are evenly applied to the contact portion of the outer peripheral edge portion 18 of the member B12 in each pressing claw 3 depending on the inclination angle. In addition, the member B12 does not shift in the horizontal direction, and is only pressed in the vertical direction.
以下レーザ溶接機にその押圧状態のまま全体をセットさ
