    Abstract: An improved apparatus and method for vacuum fusion bonding of large, patterned glass plates. One or both glass plates are patterned with etched features such as microstructure capillaries and a vacuum pumpout moat, with one plate having at least one hole therethrough for communication with a vacuum pumpout fixture. High accuracy alignment of the plates is accomplished by a temporary clamping fixture until the start of the fusion bonding heat cycle. A complete, void-free fusion bond of seamless, full-strength quality is obtained through the plates; because the glass is heated well into its softening point and because of a large, distributed force that is developed that presses the two plates together from the difference in pressure between the furnace ambient (high pressure) and the channeling and microstructures in the plates (low pressure) due to the vacuum drawn.

    Abstract: An optical fiber having optical characteristics that systematically vary along its length is made by inserting a plurality of cylindrical tablets into a cladding glass tube and overcladding the tube with particles of cladding glass. Each tablet contains a core region, and it optionally contains a layer of cladding glass Adjacent tablets are capable of forming optical fiber sections having different optical properties. Prior to consolidating the glass particles, chlorine flows through the tube and over the tablets. When the tube begins to sinter, the chlorine flow is stopped and the sintering particles generate an inwardly directed force that causes the tube to collapse inwardly onto the tablets which concurrently become fused to each other. The resultant draw blank can be drawn into a low loss optical fiber. This method is particularly useful for making dispersion managed single-mode optical fibers.

Then the temperature is kept constant at approximately the transitional temperature until the frit has become undeformable, said space (13) between the cover plates (3, 5) being fully evacuated then. Finally, cooling-down continues to room temperature, and the space (13) inside the panel is hermetically sealed off.

In one form of this method, particles of vitreous material are pressed into a mold cavity that surrounds the lead structure, thus forming a compact surrounding the lead structure. This compact is sintered in an inert atmosphere, thereby forming the sub-assembly. Thereafter, the sub-assembly is placed in an opening in the envelope, and a hermetic seal is made between the envelope and the vitreous body in the interface region between the envelope and the vitreous body.

  • Patent number: 5383948
    Abstract: This invention relates to a method and apparatus for cracking off glass attached to, or comprising a portion of, the constricted end (neck) of the glass funnel component of a glass cathode ray tube and thereafter sealing a replacement glass neck component to the funnel component. A gauge and sensor mechanism are used to produce a signal representative of the location of a defined plane through the funnel. This signal is sent to a central processing unit which controls the apparatus so that the cracking off of the old neck and subsequent sealing of the new neck take place at that defined plane. In this way, the individual method steps are integrated into an automated process.

  • Patent number: 5378183
    Abstract: An improved design and method and of manufacturing a luminous tube electrode comprises the steps of placing an electrode shell in an outer tube and allowing conductors connected to the electrode shell to emanate from an open end of the outer tube. A tubulation with a flared end is then butted up against the end of the outer tube, thereby sandwiching the conductors between the flared end of the tubulation and the outer tube. The flared end of the tubulation are then fused to one another forming a hermetic seal between each other and the conductors, resulting in the finished electrode. A further provision is made to blow a bubble in the tubulation.

  • Patent number: 5325450
    Abstract: An optical fiber coupler having a crosstalk characteristic of at least 18 dB. The optical fiber coupler includes a plurality of optical fibers. A length of glass in the optical fibers is exposed by removing the covering. The glass lengths are fused together and extended, during which time the fibers are twisted and subjected to a tension. The twisted fibers are then fixed to a protecting member while the tension is sustained.

  • Patent number: 5309536
    Abstract: The first process for producing an optical fiber coupler includes a first step wherein at least one of the optical fibers to be used is stripped of the coating, a second step in which the bare portion of that optical fiber is heated for a predetermined time to diffuse the dopants, a third step wherein the other optical fibers which have not been heat-treated are stripped of their coating, a fourth step in which the bare portions of all the optical fibers are heated as they are brought into intimate contact, thereby forming a unitary portion, and a fifth step wherein the unitary portion is drawn via heating to form the coupling portion of an optical fiber coupler.

  • Patent number: 5307245
    Abstract: An improved fiber optic backlighting panel provides uniform and increased background illumination in devices, such as rubber keypads, membrane switches, liquid crystal displays, rigid panels or the like. The fiber optic panel comprises a light source and a layer of optical fibers arranged adjacent each other, which transmit light to different locations throughout the device, thereby providing efficient background illumination relative to the amount of light beamed in. The optical fibers are selectively terminated at these locations by forming a series of angular cuts through the layer of optical fibers with a laser, according to a predetermined geometric zig-zag or sawtooth pattern stored in a computer memory. The zig-zag pattern extends across the entire length and width of the panel such that each optical fiber is cut only once to provide increased and consistent illumination throughout the device.

  • Patent number: 5304228
    Abstract: An apparatus for delivery of high intensity laser radiation of large spot size into arteries and a method for making same are disclosed. An optical radiating apparatus is formed on one end of a light-conducting optical fiber such that high intensity laser radiation leaves the optical radiation apparatus with a spot size that is expanded to a diameter significantly larger than the optical fiber diameter. The apparatus comprises a small diameter, flexible fiber which tapers to a large diameter, smooth, rounded ball tip. The taper allows the beam to expand to several millimeters in diameter and thereby ablate a large channel through an occluded artery. The smooth ball tip minimizes the chance of mechanical dissection or performation. The fiber material is continuous such that there are no optical interfaces.

  • Patent number: 5295210
    Abstract: An achromatic fiber optic coupler of the type wherein three single-mode optical fibers are fused together along a portion of the lengths thereof to form a coupling region. Each fiber includes a core and a cladding, the lowest refractive index of the fiber claddings being n.sub.2. The fibers are disposed in a triangular array in the coupling region. A matrix glass body of refractive index n.sub.3 surrounds the coupling region, n.sub.3 being lower than n.sub.2 by such an amount that the value of .DELTA..sub.2-3 is less than 0.125%, wherein .DELTA..sub.2-3 equals (n.sub.2.sup.2' -n.sub.3.sup.2)/2n.sub.2.sup.2.

  • Patent number: 5295205
    Abstract: A monolithic, environmentally stable Mach-Zehnder device is formed by threading first and second dissimilar optical fibers through the bore of a glass tube. The tube is evacuated and heated to collapse it onto the fibers. The tube is further heated and stretched at two spaced locations to form two couplers that are joined by the two optical fibers. The fibers have different propagation constants in the region between the two couplers, whereby there is a relative delay in the optical signal propagating in one of the fibers with respect to the optical signal propagating in the other fiber.
