    摘要: A borosilicate glass composition comprises SiO2 having a concentration of about 40 mole percent to about 60 mole percent, B2O3 having a concentration of about 10 mole percent to about 30 mole percent, and an alkaline earth and/or alkali compound having a concentration of 10 mole percent to about 40 mole percent. An optical fiber amplification device comprises a borosilicate glass material cladding. The core comprises a germanate glass material doped with Tm3+. The germanate glass material has a first surface configured to receive an optical signal having a wavelength of from about 1400 nm to about 1540 nm and a second surface configured to output an amplified optical signal. In this manner, low cost fiber amplifiers in the 1450-1530 nm wavelength region (corresponding to the S-band) can be achieved.

    摘要: A near-net or net shape fused silica glass article, such as a radome. The article is formed by depositing silica soot onto a mandrel having a shape that corresponds to the shape of the fused silica glass article. In some embodiments, the mandrel is inductively heated to a temperature that is sufficient to consolidate or sinter the silica soot upon deposition onto the mandrel to form fused silica glass. The fused silica glass article may have an outer layer that is under compression and/or multiple layers comprising various dopants that can alter or affect physical, mechanical, electrical, and/or optical properties.

    摘要: A method of forming a preform which has a glass core (54) surrounded by an outer glass cladding (52) with a coating of a particulate optically active material (12) 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 coherent coating of an optically active particulate material (12) over the surface of the core, with the coating material (52) having a viscosity which is equal to or less than the viscosity of the glass core (54). A glass cladding (52) is formed over the coated layer, with the cladding glass (52) having a viscosity which overlaps the viscosity of the core glass (54). The optically active material is an inorganic material which includes a metal, metal alloy, ferrite, magnetic material and a semiconductor. The invention includes the product formed by the process.

    摘要: 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 Pr and/or Dy in a concentration range of between 300 - 2,000 ppmw and Ag in a concentration range of between 500 - 2,000 ppmw; or Er 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.

    摘要: Filament in tube and stick in tube processes of forming optical fiber are described. A solid or monolithic core feedstock (110) is disposed in a hollow cladding structure (112) to form a loosely filled cladding structure. The filled cladding structure is heated to a draw temperature approximately equal to the softening temperature of the cladding structure. The feedstock (110) melts and fills the heated portion of the cladding structure forming a filled core which can then be drawn into optical fiber or to an optical can which can then be further overclad consolidated and drawn into fiber. Feedstock (110) and cladding structures (112) having widely varying coefficients of expansion may be employed. The resulting fiber can be readily designed to be fused to existing installed fibers.

    摘要: 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 mu m 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.
