摘要： Method and apparatus for providing a linearly tapered bore in quartz/glass tubing includes a laser and elements for focusing the laser onto the glass tubing. The glass/quartz tubing is rotated in the laser beam and is moved vertically in the laser beam to provide a linear taper in the interior bore. The power of the laser beam is controlled and the laser beam is appropriately focused by a lens to provide a desired width of the beam at the glass/quartz tubing.

摘要： Apparatus for optically coupling first and second optical fiber segments comprises a base frame (10), a support (14, 18) for supporting the second fiber segment relative to the base frame in an orientation in which its central axis is aligned with a horizontal optical axis (72), and a first displacement mechanism (40-64) for supporting the first fiber segment in a coaxially aligned relationship with the second fiber segment. The first displacement mechanism is operable selectively to displace the first fiber segment along the horizontal optical axis. A cup (122) contains a bath of index-matching liquid and is supported at a position below the horizontal optical axis. A second displacement mechanism (108, 110) supports a dipper (114, 118) so that the dipper is displaceable along a path such that a drop retaining portion of the dipper is first placed within the cup and is then raised so that the drop retaining portion of the dipper lies on the horizontal optical axis.

摘要： A fiber chuck comprising a rod made of a vitreous material having a fiber groove for an optical fiber. The optical fiber lies in the fiber groove, and a clamping mechanism holds the optical fiber in place. The fiber holding chuck positions the optical fiber without damaging the fiber in order to align the fiber with another fiber. The clamping mechanism maintains the position of the aligned fiber. Preferably, the fiber chuck mounts in a chuck groove of a chuck mounting fixture. The chuck mounting fixture can attach to a fiber positioning mechanism, and the positioning mechanism positions the chuck mounting fixture along with the fiber chuck and the optical fiber to align and splice two optical fibers together while reducing the risk of damage to the optical fibers.

摘要： The present invention is an apparatus for holding a first cable and a second cable in communication on an object. The apparatus includes a first member for holding a first end of the first cable and a second member for holding a second end of the second cable. The second member is disposed in a predetermined adjacent relationship with the first member such that the first and second ends are abutted up against each other and can communicate a signal therebetween. The apparatus also has means for affixing each of the first and second members separately to the object in the predetermined adjacent relationship. Preferably, the cables are fiber optic cables and the signal is light. In an alternative, the first and second members are fixedly attached to a spring base. The spring base is for maintaining the members in the predetermined adjacent relationship such that the first and second ends are abutted and can communicate a signal therebetween when the object is on the apparatus.

摘要： Throughput between two objects of light or another physical quantity having a substantially unimodal throughput profile in terms of relative orientation of said objects, is maximized. To this end, the physical quantity is initially transmitted between the objects at other than optimum throughput in the substantially unimodal throughput profile, and relative movement in loops in the substantially unimodal throughput profile is imposed on the objects. Throughput intensities are detected at different specific points along the loops, and detected throughput intensities are arranged at corresponding different specific points in an array, from which the relative orientation of the objects at which a maximum throughput has occurred is identified. A discrepancy may be displayed or the objects are moved unto that optimum relative orientation. The process may be reiterated until maximum throughput has been achieved, at least within an acceptable tolerance.

摘要： The splice verification system of the present invention verifies the efficiency of an optical splice by measuring the scattered light escaping from the splice. Specifically, the preferred embodiment performs such scattered light measurement within a photodetection area which is substantially free of all ambient light. Furthermore, the verification system includes a reference power module which, prior to creating an optical splice, measures the level of the optical signal being transmitted out of the end of an active fiber. The present invention then provides means to correlate the level gauged as a reference signal level relative to the amount of scattered light lost from the optical splice. The ratio of these two measured light levels may then be used to determine whether the amount of scattered light lost from the optical splice is acceptable given the particular constraints of the optical system in which the splice is employed.

摘要： An optical fiber containing intrinsic alignment features is disclosed. The fiber comprises a core, cladding layer, cladding insert or inserts, and a jacket. The outer shape of the tip of a fiber can be altered by etching away the jacket and cladding insert or inserts. The respective solubilities of the cladding insert and the cladding layer in etchants are selected to provide control of the resulting fiber shape upon completion of etching.

摘要： The present invention is directed to a heat shrink clad core optical conduit and to an optical conduit having either a thermoplastic, thermoset or liquid, light transmitting core surrounded by, preferably a fluoropolymer cladding which is in turn surrounded by a tight-fitting, finish polymer jacket which may be either transparent or translucent, and is preferably made of a polyvinyl chloride, polycarbonate, acrylic or silicone material. Numerous fillers and inserts may be used in the finish jacket polymer and the finish jacket polymer may be formed into various shapes. Bondable jacket materials may be used. The preferred method of forming the manufacturing jacket around a heat shrinkable fluoropolymer cladding is by extruding a low extrusion temperature polymer over a heat shrink clad in its expanded form into which an increased interior pressure is maintained to prevent shrinkage during the extrusion process. The preferred method of forming the finish jacket around a base clad core material is by an extrusion process where the finish jacket material is extruded over a heat shrink type fluoropolymer clad, in its expanded form, cured thermoset core thereby simultaneously shrinking the clad.

摘要： A method of forming a tapered aperture at the end of a capillary tube bore. A gaseous etchant such as a fluorine-containing compound flows through the bore and emanates from the first end of the tube. That tube end is heated to create a longitudinal temperature gradient. The gaseous etchant reacts with the tube and enlarges that portion of the bore at the first end. The resultant tapered aperture has a surface smoothness and shape that greatly facilitates the insertion of optical fibers during the fabrication of optical energy transfer devices.

摘要： The present invention is directed to a device and method for precise positioning, or alignment of one or more articles with respect to the device or to each other. The device comprises one or more elements of Unistructural Mass of Inherent Memory Polymer with one or more internal cavities which have inherent shapes with at least one cross-sectional configuration which is congruent to a cross-sectional configuration shape of the said article(s) in the positioned or aligned position(s). The unistructural mass has cross-sectional configurations which are the same or smaller than those corresponding to the positions of the articles. The unistructural mass is deformed such that the articles can be readily inserted into the corresponding cavities. In one embodiment, a single unistructural mass has a single cavity for precision positioning of the article. In another embodiment, the mass has at least two cavities for article alignment. In another embodiment, a plurality of unistructural masses are aligned or connected and each contains at least one such cavity. Once the articles are inserted into their corresponding cavities, the inherent memory polymer is returned to its inherent shape by non-mechanical stimulus to force the articles into precisely defined position.
