Abstract: The present disclosure relates to the field of microelectronic die packaging, particularly multi-chip packaging, wherein on-substrate modularity is enabled by using in-street die-to-die interconnects to facilitate signal routing between microelectronic dice. These in-street die-to-die interconnects may allow for manufacturing of several products on a single microelectronic substrate, which may lead to improved microelectronic die and/or microelectronic module harvesting and increased product yields.

Abstract: An improved method and apparatus is disclosed for sintering large, cylindrical, porous bodies used in the manufacture of high-quality optical fiber preforms. The apparatus has a compact, simplified structure, as compared to comparable apparatus of the prior art. The apparatus includes two separate support/slide assemblies that support the porous body throughout the sintering process. A first support/slide assembly engages a special handle for the porous body during a first stage of the process, in which the body is lowered into a furnace muffle. A second support/slide assembly then engages the porous body's handle during a second stage of the process, in which the body is controllably moved through a hot zone of the furnace, for dehydration and sintering of the body into a dense glass optical fiber preform. The body's handle is specially configured to allow both support/slide assemblies to be engaged with it simultaneously, whereby the sintering process can be carried out without the need for separate support structure during the switchover from the first support/slide assembly to the second support/slide assembly.

Abstract: An improved sol-gel process for fabricating large, crack-free gel monoliths (e.g., of silica) is described in which a specially-tailored gel microstructure is provided by adjusting the relative concentrations of an alcohol diluent (e.g., ethanol) and/or one or more catalysts (e.g., HCl and HF). Controlled variations in the gel's average pore radius, bulk density, rupture modulus, and elastic modulus over a wide range can be tailored in this fashion. This enables the process to be optimized for the particular application involved.

Abstract: A process for manufacturing a preform from which is drawn an optical fiber, the core of which comprises layers of different glass composition. In one embodiment, the known CVD process for making preforms is modified by halting rotation of the substrate tube while the tube is asymmetrically heated by a source that traverses the length of the tube. A vapor mixture flowing through the tube reacts only near that region of the inner surface of the tube that is being heated. This forms a longitudinal strip of glass particles. The flow of reactants stops, the tube is rotated, and it is traversed by heating means which heats the tube to a temperature sufficiently high to fuse the glass particles and forming a longitudinal strip of glassy material.

Abstract: A glass optical waveguide filament preform is prepared by chemical reaction of vapor ingredients within a glass bait tube. As the reactants flow through the bait tube, a hot zone traverses the tube to cause the deposition of sooty reaction products in the region immediately downstream of the hot zone. A baffle tube extends into that end of the bait tube into which the reactants flow. The baffle tube, which traverses the bait tube along with the burner, ends just short of the hot zone so that no soot is deposited thereon. A gas flowing from the baffle tube creates a gaseous mandrel which confines the flow of reactant vapors to an annular channel adjacent the bait tube wall in the hot zone, thereby increasing deposition rate and efficiency.

Abstract: This specification describes a novel apparatus and method for testing optical wave guides to determine the optical attenuation and to locate faults in the optical fiber. The light for test purposes is launched into the fiber by one or more light beams that surround the wave guides and that are focussed to converge from around the circumference and at the axis of the wave guide; the convergence being at low angles of incidence, so that some of the light enters the wave guide. The remaining light launched into the wave guide in opposite directions at a location, nearer to one end than to the other, is measured at opposite ends of the wave guide. The ratio of the light at the opposite ends of the wave guide and the difference in the length of travel of the light from the region of entry to each end is used to compute attenuation. Faults are found by internal reflections of the light beam in the wave guide.

Abstract: This optical fiber cable has the optical fibers adhered to a support. An assembly including the fibers and the support is carried by a core element having a helical channel in which the fiber assembly is located and free to adjust itself to accommodate bending of the cable without subjecting the optical fibers to pressure or to bends that are excessively sharp. The construction also avoids pressure on the optical fibers from binders, core tapes, or the cable sheath when the cable is bent. It also avoids micro-bending losses. Locating of the optical fibers closer to the cable axis further decreases bending losses.

Abstract: A sol-gel process is disclosed for depositing multi-layer antireflection coatings on plastic substrates. One or more polymerized, titanium-containing solutions are provided by mixing a titanium alkoxide, an alcohol, and water, and one or more polymerized, silicon-containing solutions are provided by mixing a silicon alkoxide, an alcohol, and water. These solutions are applied to the plastic substrate in an alternating fashion, to produce a succession of uniform layers of polymerized titanium dioxide and polymerized silicon dioxide. Each layer is individually cured before the next layer is applied. The resulting coating of multiple polymerized layers provides very low reflectance over the entire visible wavelength range, yet with excellent mechanical strength and durability.
