摘要： Liquid supply apparatus is disclosed for continuously supplying a two-package liquid polymer coating exhibiting rapid gelling and curing characteristics to an optical fiber coater for application to a glass optical fiber being drawn therethrough. The apparatus comprises: first and second metered liquid supply means (12, 14, 16 and 22, 24, 26) for continuously suppyling metered proportions of first and second liquid polymer components (A,B) of the liquid polymer coating, at least one of said metered liquid supply means comprising a feedback signal (50, 46 and 60, 56) input for receiving a control signal for controlling the rate of supply of liquid polymer component therefrom; a liquid mixer (32) connected to both the first and second metered liquid supply means for continuously combining and mixing together the first and second liquid polymer components supplied from the supply means, thus to provide a polymerizable coating liquid; a mixer output conduit (34) connecting the liquid mixer (32) to the optical fiber coater (40) for transporting the polymerizable coating liquid from the mixer (32) to the coater (40); sensing means (42) positioned at or downstream of at least one of the metered liquid supply means for generating a depletion signal in response to the depletion of polymerizable coating liquid from the coater; and signal transmission means connecting the sensing means (42) with the feedback signal input for transmitting the depletion signal from the sensor to the feedback signal input, said depletion signal operating to control the rate of supply of liquid polymer coating components from the metered liquid supply means to the liquid mixer.

摘要： A rigid, low expansion formable housing composition can be used to package optical waveguide couplers. The housing is in intimate contact with and strongly bonded to the coupler being packaged. The housing composition includes a formable polymeric resin, a glass-ceramic or ceramic or glass filler, and, optionally, strengthening fibers. The filler has a low thermal expansion to compensate for the high expansion of the resin. A moisture barrier layer may be placed around the housing composition, and it is possible to incorporate a shock absorbing material between the housing and the moisture barrier layer.

摘要： Disclosed is a fiber amplifier system including a gain fiber having a single-mode core doped with active dopant ions capable of producing stimulated emission of light at wavelength lambda s when pumped with light of wavelength lambda p. Spliced to the gain fiber is a light-attenuating fiber having a core containing a dopant that attenuates light of wavelength lambda p but not lambda s. The amplifier is conventionally employed in a system including an incoming telecommunication fiber for introducing light of wavelength lambda s into an end of the gain fiber, the amplified signal being connected to an outgoing telecommunication fiber. The system further includes a pump source for introducing light of wavelength lambda p into an end of the gain fiber. Elements of the system can be arranged for forward pumping, counter pumping and dual ended pumping. Various interconnection schemes are disclosed for forming a series arrangement including the gain fiber, the attenuating fiber and the outgoing fiber.

摘要： Disclosed is a method and apparatus for drawing an elongated glass article (32) such as a fiber optic device. The article (32) is drawn upwardly from a source (28) through the surface of a quantity of molten metal (21) having a vertical temperature gradient. The source can be an elongated solid glass preform (28) that is vertically positioned within the molten metal (21) such that the temperature of that portion of the molten metal adjacent the upper end region is sufficiently high to heat that region to drawing temperature. The upper end region (29) is pulled to form a tapered root, continued pulling resulting in the formation of an elongated article (32) from the small diameter root end. The relative position of the root is maintained with respect to the surface of the molten metal during the drawing operation. Alternatively, the glass can be drawn from an orifice located within the molten metal. The apparatus includes container means (11,12) for supporting the molten metal (21), and external or internal means (22,23) for heating and/or cooling portions of the molten metal (21). The container (11,12) can also be provided with baffle means for dividing the container into a plurality of chambers.

摘要： The coupler comprises two waveguides imbedded in a substrate and exhibiting a coupling region of length L establishing coupling coefficients (C1) and (C2) for the signals of the wavelengths ( lambda 1) and ( lambda 2) respectively. Following the invention, the length (L) and the coefficients (C1) and (C2) are linked by the relationship: C1.L=n pi DIVIDED 2 and C2.L=m pi DIVIDED 2 where n and m are integers, one uneven and the other even, chosen in such a manner as to establish a pass band of predetermined width (BP1, BP2) around at least one of the wavelengths ( lambda 1) and ( lambda 2). Application to multiplexers/demultiplexers for optical fiber telecommunications.

摘要： Optical waveguide paths are formed under the surface of a glass substrate by a method comprising (a) forming by ion-exchange a dopant ion path on a first substrate surface, (b) applying an electrode to the second surface, (c) contacting the first surface with a molten salt bath, and (d) applying an electrical field across the substrate to drive the dopant ions deeper into the substrate. The current resulting from high fields can overheat the substrate, thereby causing substrate warping and burying of paths to uneven depths. One aspect of the invention involves cooling the substrate by flowing the molten salt along the first surface of the substrate at a sufficient rate of flow to adequately decrease its temperature and by rapidly flowing the furnace atmosphere over the surface of the substrate. A further aspect of the invention involves initially applying a voltage Vi across the substrate, allowing the current to increase to a predetermined level Im, and maintaining the flow of current at the predetermined level Im by decreasing the applied voltage at a rate necessarry to maintain the current at level Im. The electrical field remains for a predetermined period of time to bury the ion path a predetermined depth.

摘要： The disclosed invention relates generally to laboratory ware, and specifically to laboratory ware and method for cultivating biological cell cultures within the laboratory ware. Cell culture vessels are disclosed providing enhanced cell yields for epithelial-like cell lines, and a more in-vivo like cell growing environment for fibroblast-like cell lines. A representative flask and dish including a plurality of grooves, or valleys, residing between ridges substantially covering the interior of preferably the bottom wall of the flask and dish is disclosed. The preferred ridges have a radius between 0.1 and 0.5 millimeters and range from 0.2 to 2.0 millimeters in height, and are spaced apart from each other within the range of 0.2 to 2.5 millimeters.
