摘要： 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.

摘要： A high density optical fiber array assembly and assembly method includes a housing securing a front array mask etched with extreme precision to define openings arranged in a predetermined pattern. A series of guide plates form a series of fiber guide channels that align with the mask openings, which plates are stacked within the housing so that the bottom of one acts as a cover for the channels of another. Fibers can be tool inserted along the channels as one group, such as a row of fibers, or manually inserted and advanced sequentially. Alternately, the mask and guide plate stack are mounted to and within a mounting block and the mounting block assembly inserted into the assembly housing substantially all remaining voids in the housing are filled with bonding material.

摘要： A system of making high density optical fiber arrays that includes securing the optical fiber ends in the housing front mask openings, then lapping the fiber ends and front mask forward surface to angle the fiber end front surfaces so that reflected wave energy does not interfere with optical signal data when transmitted during use. The opening pattern is preferably 2×2 to 128×128 or higher. Several alternate lap tool designs are disclosed including translational and rotating laps formed from solid bodies or a series of stacked plates. Standard slurry grinding and polishing compounds can be applied as desired. If a layer of epoxy originally covers the mask front face, it is removed by the lap tool as the fiber ends are lapped.

摘要： 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.

摘要： 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.

摘要： Solar resistant fused silica optical fiber is made by heating the starter rod, drawing the fiber, and preferably immediately diffusing hydrogen into the fiber, then promptly covering the hydrogen diffused fiber with hermetic coating to trap the hydrogen within the fiber. The presence of hydrogen in the fiber neutralizes UV radiation induced defects and because the hydrogen can only migrate through the fiber ends, the life of the solar resistant fiber for transmission wavelengths is increased by several years over conventional solar resistant fiber.

摘要： An optical system transmits and reflects a laser beam along a common optical path between a laser generator and the target area on a workpiece. Illuminating light is transmitted along a portion of the optical path to the workpiece and is reflected therefrom to form an image of the target area projected onto a display screen. The reflected laser beam is focused at a detection point to monitor etch rate while the illuminating light is reflected adjacent thereto from the optical path to provide a visual indication of the laser beam locations on the workpiece corresponding to the image being simultaneously displayed.

摘要： An optical fiber tap is described which comprises a beamsplitter formed by positioning bevelled, parallel endfaces of two segments of optical fiber in coaxial alignment and in close proximity to each other. A suitable dielectric film, such as air, fills the gap between the endfaces. Light propagating into the tap from the first fiber segment is partially reflected and partially refracted at the bevelled endfaces. The refracted portion enters the second fiber segment and the reflected portion leaves the tap and is detected by a photodetector. By choice of the proper angle for the bevelled endfaces, the tap can be made substantially mode independent. A greater degree of mode independence can be obtained by interposing a steady-state mode exciter between the light source and the beamsplitter. The tap is particularly useful for semiconductor junction laser stabilization by the feedback arrangement described herein since the ratio of the intensity of the reflected portion to that of the refracted portion is substantially constant. A package assembly for use in the feedback arrangement is also described.
摘要翻译：描述了一种光纤抽头，其包括通过将两个光纤段的平行端面以同轴对准并且彼此靠近的方式定位成倾斜的平行端面而形成的分束器。诸如空气的合适的介电膜填充端面之间的间隙。从第一纤维段传播到龙头中的光部分地被反射并在倾斜的端面部分地折射。折射部分进入第二光纤段，反射部分离开水龙头并由光电检测器检测。通过选择倾斜端面的适当角度，可以使水龙头基本上与模式无关。通过在光源和分束器之间插入稳态模式激励器可以获得更大程度的模式独立性。由于反射部分的强度与折射部分的强度之比基本上是恒定的，因此通过本文所述的反馈装置对于半导体结激光器稳定性特别有用。还描述了用于反馈布置的封装组件。
