摘要： The present invention is directed to a method for forming glass articles containing enclosed channels. The method comprises the flollowing steps: a) delivering and depositing a first length of a molten glass ribbon (18) to a surface of a mold (20) having a modl cavity (22) possessing at least one channel-forming groove (22) and a peripheral surface, wherein the first length (18) overlies the mold cavity (22) and the peripheral surface; b) allowing the first length of the molten glass ribbon (18) to substantially conform to the contour of the mold cavity (22) resulting in the formation of at least one channel in the first length of the molten glass ribbon (18); c) delivering and depositing a second length of the molten glass ribbon (26) to the exposed surface of the first length of the molten glass ribbon (18). The delivered molten glass viscosity of the molten glass ribbon (18, 26) is such that the following is achieved: 1) the second length (26) bridges but does not sag into complete contact with the channel portion of the earlier-deposited first length (18); and, 2) a hermetic seal is formed wherever the molten glass' first (18) and second lengths (26) contact.

摘要： Disclosed is an optical fiber having a core with an alkali metal oxide dopant in an peak amount greater than about 0.002 wt. % and less than about 0.1 wt. %. The alkali metal oxide concentration varies with a radius of the optical fiber. By appropriately selecting the concentration of alkali metal oxide dopant in the core and the cladding, a low loss optical fiber may be obtained. Also disclosed are several methods of making the optical fiber including the steps of forming an alkali metal oxide-doped rod, and adding additional glass to form a draw perform. Preferably, the draw preform has a final outer dimension (d2), wherein an outer dimension (d1) of the rod is less than or equal to 0.06 times the final outer dimension (d2). In a preferred embodiment, the alkali metal oxide-doped rod is inserted into the centerline hole of a preform to form an assembly.
