    • An optical device structure for use where an optical fiber requires to be accurately aligned in an optically coupled relationship with another optical component in a package 100 comprises an optical fiber 16 mounted in a feedthrough tube 9 which is aligned with a laser 6 through an aperture 18 in a wall 4 of the package 100. The alignment is held by a first alignment means 10, in this case a sleeve spool, which is secured to the wall 4 and to the feedthrough tube 9 relatively close to the wall 4, and by a second alignment means 11, in this case a tubular bushing, which is also fixed to the wall 4 and to the feedthrough tube 9 in a region remote from the wall 4. The use of the two alignment means 10, 11 fixed in this manner permits the desired optical coupling to be accurately fine-tuned in fabrication by a novel technique.
    • 一种用于光纤需要与封装100中的另一光学部件的光学耦合关系精确对准的光学器件结构包括安装在馈通管9中的光纤16,馈通管9通过孔18对准激光器6 在该封套100的壁4中。对准由第一对准装置10保持,在这种情况下是套筒卷轴,其被固定到相对靠近壁4的壁4和馈通管9上, 第二对准装置11,在这种情况下是管状衬套,其也在远离壁4的区域中固定到壁4和馈通管9上。以这种方式固定的两个对准装置10,11的使用允许 所需的光学耦合在通过新技术的制造中被精确地微调。
