Abstract: A laminated glass article includes a core layer and a clad layer directly adjacent to the core layer. The core layer is formed from a core glass composition. The clad layer is formed from a clad glass composition. An average clad coefficient of thermal expansion (CTE) is less than an average core CTE such that the clad layer is in compression and the core layer is in tension. A compressive stress of the clad layer decreases with increasing distance from an outer surface of the clad layer within an outer portion of the clad layer and remains substantially constant with increasing distance from the outer surface of the clad layer within an intermediate portion of the clad layer disposed between the outer portion and the core layer. A thickness of the intermediate portion of the clad layer is at least about 82% of a thickness of the clad layer,

Abstract: A multicore fiber is provided. The multicore fiber includes a plurality of cores spaced apart from one another, and a cladding surrounding the plurality of cores and defining a substantially rectangular or cross-sectional shape having four corners. Each corner has a radius of curvature of less than 1000 microns. The multicore fiber may be drawn from a preform in a circular draw furnace in which a ratio of a maximum cross-sectional dimension of the preform to an inside diameter of the preform to an inside diameter of the draw furnace is greater than 0.60. The multicore fiber may have maxima reference surface.

Abstract translation: 提供多芯光纤。 多芯光纤包括彼此间隔开的多个芯，以及围绕多个芯并且限定具有四个角的基本上矩形或横截面形状的包层。 每个拐角的曲率半径小于1000微米。 多芯纤维可以在圆形拉丝炉中从预成型件中拉出，其中预成型坯的最大截面尺寸与预成型坯的内径与拉制炉的内径之比大于0.60。 多芯纤维可以具有最大参考表面。
