Appl. No.:

11/008396

Inventors:

Benjamin Hanson - New York NY, US
Michael Murtagh - New York NY, US
Pushkar Tandon - New York NY, US

International Classification:

G02B006/02

US Classification:

385123000

Abstract:

Disclosed is an alkali-doped optical fiber perform and method for making the same. A silica glass member, such as a rod or the like is heated in a furnace chamber at a temperature of less than 75 C. below the softening point of the glass rod in an environment containing an alkali metal vapor to form an alkali metal oxide doped glass rod. This method provides a peak concentration in the outer half portion of the silica glass member. The alkali metal oxide doped glass member may be overclad with additional glass to form an optical fiber preform ready for drawing into an optical fiber. Alternatively, the alkali metal oxide doped glass member may be inserted into a porous, glass soot optical fiber preform or inserted into a tube comprising solid glass.

Abstract:

A method is disclosed for inhibiting oxygen and moisture penetration of a device comprising the steps of depositing a tin phosphate low liquidus temperature (LLT) inorganic material on at least a portion of the device to create a deposited tin phosphate LLT material, and heat treating the deposited LLT material in a substantially oxygen and moisture free environment to form a hermetic seal; wherein the step of depositing the LLT material comprises the use of a resistive heating element comprising tungsten. An organic electronic device is also disclosed comprising a substrate plate, at least one electronic or optoelectronic layer, and a tin phosphate LLT barrier layer, wherein the electronic or optoelectronic layer is hermetically sealed between the tin phosphate LLT barrier layer and the substrate plate. An apparatus is also disclosed having at least a portion thereof sealed with a tin phosphate LLT barrier layer.

US Classification:

Abstract:

Isopipes () for making glass sheets using a fusion process are provided. The isopipes are made from alumina materials which have low levels of the elements of group IVB of the periodic chart, i.e., Ti, Zr, and Hf, as well as low levels of Sn. In this way, the alumina isopipes can be used with glasses that contain tin (e.g., as a fining agent or as the result of the use of tin electrodes for electrical heating of molten glass) without generating unacceptable levels of tin-containing defects in the glass sheets, specifically, at the sheets' fusion lines. The alumina isopipes disclosed herein are especially beneficial when used with tin-containing glasses that exhibit low tin solubility, e.g., glasses that have (RO+RO)/AlOratios between 0.9 and 1.1, where, in mole percent on an oxide basis, (RO+RO) is the sum of the concentrations of the glass' alkaline earth and alkali metal oxides and AlOis the glass' alumina concentration.

G06F 1/16

Abstract:

The embodiments described herein relate to glass articles that include mechanically durable glass compositions having high liquidus viscosity. The glass articles may include glass compositions having from 50 mol. % to 80 mol. % SiO; from 7 mol. % to 25 mol. % AlO; from 2 mol. % to about 14 mol. % LiO; 0.4 mol. % PO; and less than or equal to 0.5 mol. % ZrO. The quantity (AlO(mol. %)−RO (mol. %)−RO (mol. %)) is greater than zero, where RO (mol. %) is the sum of the molar amounts of LiO, NaO, KO, RbO, and CsO in the glass composition and RO (mol. %) is the sum of the molar amounts of BeO, MgO, CaO, SrO, BaO, and ZnO in the glass composition. A molar ratio of (LiO (mol. %))/(RO (mol. %)) may be greater or equal to 0.5. In embodiments, the glass composition may include BO. The glass compositions are fusion formable and have high damage resistance.
