  • Method of making an optical fiber preform and handle for use in making of optical fiber preform
    Patent number: 10392291
    Abstract: A method for forming an optical fiber preform is provided. The method includes inserting a glass core cane into a glass sleeve such that the glass sleeve surrounds a portion of the glass core cane and such that there is a gap between the glass sleeve and the portion of the glass core cane surrounded by the glass sleeve. The method further includes depositing silica soot onto at least a portion of the glass core cane and at least a portion of the glass sleeve to form a silica soot preform, and flowing gas through the gap during processing of the silica soot preform.
    Type: Grant
    Filed: December 16, 2015
    Date of Patent: August 27, 2019
    Assignee: CORNING INCORPORATED
    Inventors: Raymond D. Groh, Ming-Jun Li, Alper Ozturk, Chunfeng Zhou

  • Method for forming fused silica glass using multiple burners
    Patent number: 8230701
    Abstract: A method for forming a silica glass blank includes generating soot using an array of soot producing burners, directing the soot along a first direction onto a bait, collecting the soot on the bait, imparting relative oscillatory motion having a repeat period between the array of soot producing burners and the bait along a second direction orthogonal to the first direction while collecting the soot, and offsetting the relative oscillatory motion by a selected distance along the second direction after each repeat period.
