摘要： A varied ratio coupler, and a method of forming the same, constructed and arranged, in a unitary structure, to cause optical power in an input optical fiber to couple asymmetrically to at least two output optical fibers in a manner establishing different insertion losses between the input fiber and at least two output optical fibers. The coupler includes a central fiber surrounded by a close-packed ring of fibers. In certain preferred embodiments, the coupler has a bend that lies in a preselected plane and has a radius of curvature that is selected to provide the above difference in the insertion losses.

摘要： In one aspect, the invention concerns fused fiber optic couplers of the type formed from fibers of transparent substance each having a circular cross-section of preselected diameter. The fibers include a central fiber and at least one ring of closely packed surrounding fibers with at least some of the fibers being optical fibers that have a core and a surrounding cladding. The coupler is formed by the processes of providing the fibers, assembling them in a close-packed relationship, and heating and drawing the assembly of fibers in the close-packed region.We have discovered that the steps involved in forming such a coupler, introduce slight size variations that can seriously affect the performance of the coupler, and that these slight variations can be accommodated by slight, controlled, under-sizing of one or more of the surrounding fibers or over-sizing of the central fiber.

摘要： Bends in optical fibers can be miniaturized by reducing the diameter of a section of the fiber in the region where bending is desired to a condition in which the optical properties of the fiber have reduced bend-loss sensitivity. In one aspect of the invention, radii of curvature less than 100 microns (.mu.) and very low optical power loss are achieved. A fiber with such specially reduced diameter may also be twisted about its longitudinal axis to a greater degree than a comparable length of larger diameter fiber. Any optical fiber can be processed by redrawing and/or chemical means to allow such bending or twisting. Bend or twist tolerant regions thus formed may be packaged separately or built integrally into a wide range of fiber optic components, networks, or systems with significant space savings, added performance features and mechanical flexibility.
摘要翻译：光纤中的弯曲可以通过在需要弯曲的区域中将纤维的一部分的直径减小到其中光纤的光学特性降低弯曲损耗灵敏度的条件而小型化。在本发明的一个方面，实现了小于100微米（μm）的曲率半径和非常低的光学功率损耗。具有这种特别减小直径的纤维也可以围绕其纵向轴线扭曲到比较大直径纤维的相当长度更大的程度。任何光纤可以通过重画和/或化学手段加工，以允许这种弯曲或扭曲。如此形成的弯曲或扭转宽度区域可以单独包装或整体建造到具有显着空间节省，附加性能特征和机械灵活性的广泛范围的光纤组件，网络或系统中。

摘要： A wideband single-mode fiber optic coupler and method for the fabrication of the same is provided wherein at least two fibers are joined in a fused and tapered coupling region. The taper is asymmetrical in the longitudinal extent about the midpoint of the geometric center of the fused coupling region with the difference between the fiber diameters in that region changing at a varying rate along the length of the region.

摘要： An optical coupler and method of making same is described. The coupling ratio of the coupler is polarization-insensitive. The optical coupler described herein is made from single-mode optical fibers. Each optical fiber has a length of nearly exposed core which is fused to the exposed core of the other optical fiber while the fibers are maintained in parallel juxtaposition with one another without twisting. By creating a fused core coupler from single-mode optical fibers in which the cores are in parallel juxtaposition with one another, the coupling ratio of the subject invention does not change with changes in polarization of light passing through each single-mode fiber and, thus, is polarization insensitive.

摘要： An adjustable coupling device for fiber-optic power dividers in which the coupling characteristics of the divider are influenced by application of transverse forces on the optic fibers in a repeatable fashion. The preferred embodiment consists of a pair of optical fibers which are evanescently coupled by having a portion of each etched to a core and twisted about the other. The etched and twisted portions of these fibers are encased in a rigid housing filled with an elastic filler material.

摘要： An automated fusion system includes a draw assembly for holding optical fibers and for applying a tension to the fibers. The fibers are held substantially parallel to each other in the draw assembly. The system also includes a removal station that etches or strips buffer material from the fibers after the fibers have been placed in the draw assembly, and a heater or torch assembly for heating the fibers as the draw assembly applies a tension to the fibers in a manner that causes the fibers to fuse together to form a coupler region. In addition, a packaging station is used to secure a substrate to the coupler region of the fibers to form the optical coupler.
