  • Process and device for manufacturing glass sheet
    Patent number: 7770414
    Abstract: The present invention relates to a process for manufacturing flat sheets of a glass-based material and to an apparatus therefor. The process comprises providing a glass preform, heating the glass preform in a furnace, forming a gob and a pre-sheet, removing the gob and drawing the glass pre-sheet into a flat glass sheet. Also provided is an apparatus for drawing a glass preform into a glass sheet, the apparatus comprising a draw furnace, stretching arms for stretching and drawing the pre-sheet into a glass sheet, and opposing edge rollers for applying a downward force on the glass sheet. The draw furnace may include a plurality of individual heating elements, the temperature of each heating element capable of being separately controlled. The apparatus may further include an annealing furnace for annealing the glass sheet.

  • Method to reduce warpage and polarization sensitivity of planar devices
    Patent number: 6418261
    Abstract: An optical device is provided including a substrate having an underclad layer, a core layer, and a pair of overclad layers deposited thereon. The substrate has a first coefficient of thermal expansion. The underclad layer has a first index of refraction. The first overclad layer has an index of refraction which is approximately equal to the first index of refraction. The second overclad layer has a coefficient of thermal expansion which is greater than the first coefficient of thermal expansion.
