摘要： A precision burner for oxidizing halide-free, silicon-containing compounds, such as, octamethylcyclotetrasiloxane (OMCTS), is provided. The burner includes a subassembly (13) which can be precisely mounted on a burner mounting block (107) through the use of an alignment stub (158), a raised face (162) on the burner mounting block (107), and a recess (160) in the back of the subassembly (13). The burner's face includes four concentric gas-emitting regions: a first central region (36, 90) from which exits a mixture of OMCTS and O.sub.2, a second innershield region (38, 92) from which exits N.sub.2, a third outershield region (40, 42, 94, 96) from which exits O.sub.2, and a fourth premix region (44, 98) from which exits a mixture of CH.sub.4 and O.sub.2. The burner provides more efficient utilization of halide-free, silicon-containing raw materials than prior burners.

摘要： A porous glass optical waveguide preform is formed by depositing a coating of glass particulate material on the lateral surface of a core which may be a porous glass body continuously produced by the axial deposition of glass particles. The core rotates and moves longitudinally in one direction with respect to two flame hydrolysis burners which emit streams of glass particles having different compositions. In addition, the two burners reciprocatingly move with respect to a portion of the length of the core. The speed of each burner varies as it traverses along its path of reciprocating motion. The thickness of the layer produced by a burner at a given point is inversely related to the speed of the burner as it passes that point. The layers formed by the completion of a single traverse by both burners combine to form a conically-shaped layer, the composition of which varies from the base toward the apex thereof. The conically-shaped layer, which are adjacently located longitudinally along the preform, combine to form a cylindrically-shaped portion of the preform.

摘要： Methods are provided for reducing the water content of optical waveguide fibers produced from blanks having a centerline aperture and having compositions which prevent cooling of the blank to room temperature between consolidation and drawing. In accordance with certain aspects of the invention, the water content is reduced by storing the blanks at as low a temperature as possible, preferably below about 550.degree. C. In accordance with other aspects, the water content is reduced by filling the apertures of the blanks with an inert atmosphere during storage.

摘要： A method of making low loss glass optical waveguides, wherein at least one coating of glass soot is deposited by the flame hydrolysis process on a starting member. The starting member is removed from the soot preform leaving an aperture therein. While the preform is heated to its consolidation temperature, an atmosphere including a drying agent is caused to flow into the aperture and through the porous preform, thereby removing water from the preform while the soot is consolidated to form a dense glass article. The atmosphere contains optimal amounts of oxygen and drying agent to minimize leaching of dopant oxide from the preform. Since some of the dopant oxide is leached from the preform near the aperture, the central portion of the preform is initially provided with an excess amount of dopant oxide. The resultant draw blank is drawn into an optical waveguide filament.
摘要翻译：一种制造低损耗玻璃光波导的方法，其中玻璃烟灰的至少一个涂层通过火焰水解过程沉积在起始构件上。起始构件从烟灰预制件中移除，在其中留下孔。当将预成型件加热到其固化温度时，使包括干燥剂在内的气氛流入孔中并通过多孔预型件，从而在烟炱被固结形成致密玻璃制品时从预成型件中除去水分。气氛含有最佳量的氧气和干燥剂，以最大限度地减少掺杂剂氧化物从预型体中的浸出。由于一些掺杂剂氧化物从孔附近的预制坯中浸出，所以预制件的中心部分最初设有过量的掺杂氧化物。将得到的拉丝坯拉成光波导丝。

摘要： A method of fabricating an optical waveguide fiber that includes the steps of providing a cylindrical glass optical fiber preform having a longitudinally extending centerline hole, and closing the hole under conditions suitable to result in uniform and symmetric hole closure. The method may include first plugging a first end and a second end of the centerline hole to prevent gas flow therethrough. The method preferably involves closing the centerline hole of the preform by drawing the preform down into an optical waveguide fiber.

摘要： Disclosed is a method of making a hydrogen resistant optical waveguide fiber. The soot preform is heated and then immersed in a GeCl4 gas. A reduced metal species is thus incorporated into the glass soot prior to sintering or consolidation of the soot preform. A hydrogen absorption band around 1530 nm is substantially eliminated from waveguides made from a precursor gas treated preform.
