摘要： An optical fiber assembly includes an optical fiber and ferrule. The ferrule's face is partitioned into several regions. Optical elements can be formed on the regions to diffract light incident on the ferrule. Alternatively, the ferrule's face may have several reflective facets. Light incident on the end of the optical fiber propagates to a communications detector. Light incident on the ferrule's face is redirected to tracking detectors, each arranged to receive the redirected light from a preselected region of the ferrule. The output signals of the tracking detectors are used to adjust the alignment between the incident light and the assembly. Alternatively, tracking fibers or a quadrant cell may be used to directly receive light that would otherwise be incident on the ferrule's face.

摘要： An optical coupler and method is disclosed in which a polymer material is employed to optically couple a first and second waveguide in a transfer region. In the transfer region, the first and second waveguides are positioned in parallel separated by a specific distance. The polymer material has an index of refraction which varies with temperature. The optical switch device is controlled by adjusting the temperature of the polymer material to obtain a desired index of refraction, thereby resulting in the desired transfer of an optical wave from on waveguide core to another.

摘要： Indiscriminately exciting the modes of a multi-mode optical fiber amplifier is avoided by an optical fiber amplifier design in which the excitation of pump modes in the core of a multi-mode fiber is controlled by controlling the pump light launching. The pump light is directed substantially along the center axis of a multi-mode fiber within a predetermined launch angle. Rather than exciting all modes, only lower order modes are affected.

摘要： This invention concerns with a process and apparatus for fabricating microlenses on optical fibers. A pulsed laser beam and an end portion of a fiber are arranged relative to each to another so that the laser beam is incident on the end portion of the fiber at an acute angle .theta. to the longitudinal axis of the fiber. The angle is selected to attain a desired curvature of a lens formed by ablation and heating of the end portion of the fiber by the laser beam. A movement of the fiber and the laser relative each to another results in progressive engagement of the end portion of the fiber with the laser for a preselected distance so as to produce a short taper with a lens at the end thereof. In the preferred embodiment, the fiber rotated about its axis within a passage of the holder which moves the end-portion of the fiber into and through the laser beam resulting in the said lens. The precise repeatability of the lens formation may be controlled by a computer.

摘要： Various techniques for examining the core region of optical fibers and fiber preforms involve placing a portion of the fiber/preform in an index-matching fluid and transversely illuminating the immersed portion. As described herein, the use of an index-matching fluid can be eliminated by illuminating the fiber/preform with a diverging beam. By the suitable selection of parameters, refraction at the air-fiber/preform interface can produce a well colliminated beam within the core region.

摘要： Shaping of the refractive index profile of an optical fiber is typically achieved by changing the concentration of an index-modifying dopant within the glassy matrix preform. To measure the profile and the core diameter of the preform, in accordance with the present disclosure, the preform (10) is illuminated with a focused beam of ultraviolet radiation (15) whose beam width (w) is small compared to the preform core diameter (d). This induces a fluorescence along a thin pencil-like region (16) of the preform core whose intensity varies in proportion to the concentration of the dopant. Inasmuch as the latter is proportional to the refractive index, the intensity profile gives the index profile directly. A similar measure can also be made on fibers using microscopes for focusing the uv and observing the induced fluorescence. Use of this technique for controlling the rate at which a fiber is drawn is also described.
摘要翻译：光纤的折射率分布的成形通常通过改变玻璃态基体预制件内的折射率修饰掺杂剂的浓度来实现。为了测量预型件的轮廓和芯直径，根据本公开，用聚光束的紫外线辐射（15）照射预成型件（10），其束宽度（w）比预制件芯直径小（d）。这会沿着预制核心的薄铅笔状区域（16）引起荧光，其强度与掺杂剂的浓度成比例地变化。由于后者与折射率成比例，强度分布直接给出了折射率分布。也可以使用显微镜对聚焦紫外线并观察诱导荧光的纤维进行类似的测量。还描述了使用这种技术来控制纤维被拉伸的速率。

摘要： The refractive index profile of an optical fiber preform is controlled during manufacture by illuminating the gaseous precursor being fed to the preform substrate tube with ultraviolet radiation, measuring the intensity of either the uv that traverses the gas or the induced fluorescence, comparing this measurement with a reference signal, generating an error signal, in response to this comparison, and controlling composition of the gaseous precursor in response to said error signal. A similar technique can be used to control the thickness and refractive index of each layer deposited upon the substrate tube by forming an x-ray shadowgraph of the layers as they are deposited and comparing the shadowgraph characteristics with appropriate reference signals to form a second set of error signals. The latter are then used to fine tune the fabrication process. The invention can also be employed in conjunction with the vapor axial deposition method of fabricating preforms.

摘要： The present invention provides polarization-independent optical devices by reducing or eliminating strain-induced birefrigence associated with prior device structures. In a first embodiment, an optical device is produced comprising a doped silica substrate having a coefficient of thermal expansion between 8.times.10.sup.-7 .degree. C..sup.-1 and 15.times.10.sup.-7 .degree.C..sup.-1. On the doped silica substrate is formed a doped silica waveguiding structure having a coefficient of thermal expansion between 8.times.10.sup.-7 .degree. C..sup.-1 and 15.times.10.sup.-7 .degree. C..sup.-1. Alternatively, the coefficient of thermal expansion of the doped silica substrate is selected to be approximately 90% to 110% of the coefficient of thermal expansion of the doped silica waveguiding structure. In another aspect, the present invention provides an optical device comprising a doped silica substrate having a doping gradient from a lower surface to an upper surface. The doping level at the upper surface has a coefficient of thermal expansion approximating the coefficient of thermal expansion of a doped silica waveguiding structure formed thereon.
