Abstract: The present invention relates to a glass article for use as an optical waveguide fiber (1), the core (4) of which is doped with a chalcogenide element to significantly increase the refractive index of the core (4). The subject of this invention is novel doped silica core composition wherein a portion of the oxygen in the silica is replaced with either sulfur, selenium or tellurium using plasma enhanced chemical vapor deposition (PECVD). These compositions are designed to have higher refractive indices than silica, low coefficient of expansion, high optical transparency and appropriate viscosity and softening points to make them ideal candidates for use as optical waveguide fibers.

Abstract: A method of forming a preform which has a glass core surrounded by an outer glass cladding with a coating of a light interactive material disposed between the core and cladding. The method includes providing a glass core having a viscosity which lies within a given preselected temperature range, followed by forming a substantially homogeneous coating of a light interactive material over the surface of the core, with the coating material having a viscosity which is equal to or less than the viscosity of the glass core. A glass cladding is formed over the coated layer, with the cladding glass having a viscosity which overlaps the viscosity of the core glass and a thermal coefficient of expansion compatible with that of the core. The light interactive material is an inorganic material which includes a metal, metal alloy, ferrite, magnetic material and a semiconductor.

Abstract: The present invention is directed to a fluorinated rare earth doped glass composition and method for making a glass-ceramic optical article therefrom, e.g. optical fiber waveguides, fiber lasers and active fiber amplifiers, having application in the 1300 nm and 1550 nm telecommunications windows. The inventive compositions include Pr3+ and/or Dy3+ in a concentration range of between 300 - 2,000 ppmw and Ag+ in a concentration range of between 500 - 2,000 ppmw; or Er3+ in a concentration range of between 500 - 5,000 ppmw and Ag+ in a concentration range of between 0 - 2,000 ppmw. The monovalent silver ion provides an ionic charge balanced glass-ceramic crystal. These compositions exhibit reduced or absent rare earth ion clustering and fluorescence quenching effects in the presence of high concentrations of rare earth ion dopants.

Abstract: A kink-resistant hose construction (10) adapted for conveying fluids under high pressure which is flexible intermediate a central longitudinal axis (12) to a minimum bend radius. The construction includes a thermoplastic core (14) having an inner surface (16) defining the inner diameter of the hose and an outer surface (18), and an innermost reinforcement layer (20) is formed as a composite of at least one metallic wire element and at least one non-metallic fibre element. The metallic wire element is wound helically in one direction over the outer surface of the core a predetermined pitch angle measured relative to the longitudinal axis to define a series first turns. Each of these first tuns is spaced-apart from an adjacent first turn to define successive pairs of first turns each having an interstitial area therebetween. The fiber element, in turn, is wound helically over the outer surface of the core in the same direction and at the same pitch angle as the metallic wire element to define a series of second turns each disposed intermediate a corresponding one of the pairs of the first turns or the wire element. The fiber element substantially occupies the interstitial area between each of the pairs of the first turns of the wire element to thereby prevent the wall of the core from being extruded therebetween as the hose is flexed to its minimum bend radius.

Abstract: Disclosed is an optical device (10) and a method for preparing refracted microlenses (18) in a single step, utilizing laser-induced surface structure formation in semiconductor doped glasses (SDG's). The SDG materials, in conjunction with above-bandgap wavelength laser sources, used to fabricate lenses that operate with light of below-bandgap wavelengths. In accordance with the teaching of this invention, lenses on approximately 5-500 νm diameter scale are fabricated individually or arrays by laser irradiation of absorbing glasses. The microlenses have controllable characteristics and can be fabricated to have focal lengths as short as tens of microns. The lenses are generally parabolic or spherical in shape and are highly reproducible. This invention also teaches a method for fabricating a microlens within a window of a laser diode assembly, and a laser diode assembly fabricated in accordance with the method.
