    • Optical fiber array apparatus comprising housing front mask having a matrix of fiber seating openings each opening having one or more side walls. An optical fiber extends through each opening and means presses the fiber side surface into engagement with the one or more side walls to precisely position and secure the fiber. Bonding material then fills all voids in and around the opeining. In one embodiment, a clamping wafer behind the front mask moves to clamp the fibers to the front mask opening walls. In another, the front mask defines flexing arms with distal ends that clamp fibers to opening walls and in yet another elongated flexible members lie along front mask slots to clamp fibers in openings that communicate into the slots.
    • 光纤阵列装置,包括壳体前掩模,其具有纤维座的开口,每个开口具有一个或多个侧壁。 光纤延伸穿过每个开口,并且装置将纤维侧表面挤压成与一个或多个侧壁接合以精确地定位和固定光纤。 粘合材料然后填充所有的孔隙,并在其周围。 在一个实施例中,前掩模后面的夹紧晶片移动以将纤维夹持到前掩模开口壁。 另一方面,前掩模定义了具有远端的弯曲臂,其将纤维夹紧到开口壁,并且在另一个细长的柔性构件中沿着前掩模狭槽倾斜以将纤维夹在与槽沟通的开口中。

    • A process for hermetically sealing an optical fiber to a metal housing is described. An optical fiber 12 is threaded through a thick-walled metal tube 10 which has a bore 11 of slightly larger diameter than the fiber. The tube and fiber are inserted in a pneumatically operated collet and uniform radial pressure is applied to the tube to form a unitary hermetic assembly. Metal tube 10 is characterized in that it has or, prior to forming the assembly, is annealed to have a Rockwell hardness of less that 15 T 15. At this value the metal is soft and the pressure required to cause the metal to cold flow around the fiber is less than that required to break the fiber. The tube is then soldered or otherwise secured in a hole in the housing, thus completing the hermetic seal. Such a seal is useful in hermetic packaging of optical devices. It is advantageous over the prior art for its simplicity and inexpensiveness. The technique is suited to high yield mass production of reliable seals.
    • 描述了将光纤气密地密封到金属外壳的工艺。 光纤12穿过厚壁的金属管10,其具有比光纤稍大的直径的孔11。 将管和纤维插入气动操作的夹头中,并将均匀的径向压力施加到管上以形成整体密封组件。 金属管10的特征在于,其具有或者在组装之前被退火以具有小于15T 15的洛氏硬度。在该值下,金属是软的,并且导致金属冷却流动所需的压力 纤维比破碎纤维所需的纤维少。 然后将管子焊接或以其他方式固定在壳体中的孔中,从而完成气密密封。 这种密封件可用于光学装置的气密封装。 由于其简单性和廉价性,优于现有技术。 该技术适用于高产量大量生产可靠的密封件。

    • An optical fiber array connector in which the tolerance of the diameter of the mask openings are not factors in the overall positioning of the plurality of fibers. The array includes a mask element with rear and forward surfaces and a plurality of openings that communicate through these surfaces. A plurality of optical fibers include fiber ends having substantially truncated conical side surfaces that extend through the openings and engage the portions of the mask openings nearest the mask rear surface. A method includes preparing the fibers to form a conical surface at their distal ends, preparing the openings in the primary mask each with a diameter less than the diameter of the fiber cladding or second layer, inserting the conical fiber ends until the conical surfaces engage the mask opening walls, applying bonding material to the mask forward surface and exposed tips, grinding and polishing the exposed tips and bonding material surface to truncate the cones and expose the fiber core diameters.
    • 一种光纤阵列连接器,其中掩模开口的直径的公差不是多个光纤的整体定位中的因素。 该阵列包括具有后表面和前表面的掩模元件和通过这些表面连通的多个开口。 多根光纤包括具有基本上截头圆锥形侧表面的纤维端,其延伸穿过开口并且接合最靠近掩模背面的掩模开口的部分。 一种方法包括制备纤维以在其远端处形成圆锥形表面,在初级掩模中制备各自具有小于纤维包层或第二层直径的直径的孔,插入锥形纤维末端,直到锥形表面接合 掩模开口壁,将掩模材料施加到掩模前表面和暴露的尖端,研磨和抛光暴露的尖端并粘合材料表面以截断锥体并暴露纤芯直径。
