摘要： A system and method for making an edge section of a thin, high purity fused silica glass sheet. The method includes a step of directing a laser to melt through the glass sheet with localized heating of a narrow portion of the glass sheet to form an edge section of the glass sheet, and continuing the edge section to form a closed loop defining a perimeter of the glass sheet. The method further includes rapidly cooling the glass sheet through the glass transition temperature as the melted glass of the edge section contracts and/or solidifies to form an unrefined-bullnose shape extending between first and second major surfaces of the glass sheet.

摘要： The present disclosure provides optical fiber preforms formed from core canes having large core-clad ratio, intermediate core-cladding assemblies, and methods for making the preforms and core cladding assemblies. The preforms are made with capped core canes. The capping material has a coefficient of thermal expansion less than the coefficient of thermal expansion of the core cane and more closely matched to or lower than the coefficient of thermal expansion of the surrounding cladding monolith in a cane-in-soot process. Presence of the cap reduces stresses that arise from differential thermal expansion of the core cane and cladding materials and leads to preforms having low defect concentration and low probability of failure during subsequent thermal processing steps.
