    • PURPOSE: To prevent the deviation of an optical axis after fixing by a method wherein an optical fiber is supported in the state that the total periphery of the optical fiber is surrounded by a fixing material in a groove or a hole provided in a supporting body.
      CONSTITUTION: A ring formed sealing wall 2 is formed at the center of a stem 1, the inside thereof is bored further deeper, and a pedestal 3 is formed at the center the bottom thereof. Then, a laser diode chip 5 is fixed on a submount 4 on this pedestal 3 by means of solder. A fiber guide 9 wherein the optical fiber 8 is inserted and fitted at the center is fitted into the guide hole 6, and is fixed on the stem 1 with an Ag paste 10. The tip (photo coupling end) of the optical fiber 8 penetrates the hole 20 provided in the supporting body 19 projected to the pedestal 3, and is fixed on the pedestal 3 of the stem 1 by means of the fixing material such as resin or solder.

    • 目的:为了防止光固化后的光轴被固定在支撑体上的凹槽或孔内的固定材料所包围的状态下被支承的方式来固定光轴的偏移。 构成:在阀杆1的中心形成有环形的密封壁2,其内部被进一步深深地钻出,底座3形成在其底部的中心。 然后,通过焊料将激光二极管芯片5固定在该基座3上的基台4上。 其中光纤8插入并安装在中心的光纤引导件9装配到引导孔6中,并用Ag膏10固定在杆1上。光纤8的尖端(光耦合端)穿透 设置在支撑体19上的孔20突出到基座3上,并通过诸如树脂或焊料的固定材料固定在杆1的基座3上。
