    Abstract: A borosilicate glass composition comprises SiO2 having a concentration of about 40 mole percent to about 60 mole percent, B2O3 having a concentration of about 10 mole percent to about 30 mole percent, and an alkaline earth and/or alkali compound having a concentration of 10 mole percent to about 40 mole percent. An optical fiber amplification device comprises a borosilicate glass material cladding. The core comprises a germanate glass material doped with Tm3+. The germanate glass material has a first surface configured to receive an optical signal having a wavelength of from about 1400 nm to about 1540 nm and a second surface configured to output an amplified optical signal. In this manner, low cost fiber amplifiers in the 1450-1530 nm wavelength region (corresponding to the S-band) can be achieved.

    Abstract: A method that provides a new way to embed rare earth fluorides into silicate (or germania-doped silica) glasses by means of solution chemistry. Embedding rare earth fluorides into a silicate (or germania-doped silica) glass comprises the following steps. First, form a porous silicate core preform. Second, submerge the preform into an aqueous solution of rare earth ions. Third, remove the preform from the solution and wash the outside surfaces of the preform. Fourth, submerge the preform into an aqueous solution of a fluorinating agent to precipitate rare earth trifluorides from the solution and deposit in the pores or on the wall of the preform. This is followed by drying.

    Abstract: An apparatus for producing a glass soot includes a first a burner having a droplet-emitting first region, a gas-emitting second region surrounding the first region, and a gas-emitting third region surrounding the second region. The first region emits a glass-forming mixture, the second region emits an inert gas, and the third region emits a combination of oxygen and a combustible gas. The apparatus further includes a combustion area having a first section proximate the first burner and a second section distal from the first burner. A glass-forming mixture is at least partially vaporized in the first section of the combustion area. The apparatus further includes at least one secondary burner having gas-emitting fourth and fifth regions. The fourth region of the secondary burner emits oxygen and the fifth region of the secondary burner emits a combustible gas. The second section of the conversion area is in communication with the fourth and fifth regions of the secondary burner, such that the glass-forming mixture is completely vaporized and converted into a glass soot deposited on a preform such as a bait rod. The invention also includes a method of enhanced vaporization using first and second spaced apart combustion areas.

    Abstract: Procedures are disclosed for producing both core-cladding optical fibers and self-focusing optical fibers from porous germinate and/or silicate glasses obtained after phase separation and removal of the soluble phase. A glass which is separable into at least two phases one of which is soluble, is heated to cause phase separation. The soluble phase is leached out removing undesired impurities. The pores are collapsed and this glass is used to produce cores and/or cladding layers, or self focusing fibers. According to one aspect of the invention, preforms of the porous glass have their interconnected pores stuffed with a dopant. In the production of core-cladding optical fibers, the dopant modifies the index of refraction of the core and/or cladding so that the index of refraction of the core is greater than that of the cladding. The control of this index of refraction can be accomplished by addition of non silicate network formers such as GeO.sub.2 to the original melt before phase separation. These network formers will stay in the insoluble phase. In producing self-focusing fibers, the dopant may be non-uniformly deposited in order to produce a radial gradient in the index of refraction, or sodium or potassium ions may be ion exchanged into the glass for a portion of a dopant containing lithium or thallium to produce such an index of refraction gradient.

    Abstract translation: 公开了用于在相分离和去除可溶相之后获得的多孔发芽体和/或硅酸盐玻璃中生产芯包层光纤和自聚焦光纤的方法。 可分离成至少两相的玻璃是可溶的，被加热以引起相分离。 浸出溶出相去除不需要的杂质。 孔被折叠，并且该玻璃用于生产芯和/或包层或自聚焦纤维。 根据本发明的一个方面，多孔玻璃的预制件具有填充有掺杂剂的互连孔。 在芯包层光纤的生产中，掺杂剂改变了芯和/或包层的折射率，使得芯的折射率大于包层的折射率。 该折射率的控制可以通过在相分离之前向原始熔体中添加诸如GeO 2的非硅酸盐网络形成剂来实现。 这些网络成员将保持在不溶性阶段。 在生产自聚焦纤维时，可以不均匀地沉积掺杂剂以产生折射率的径向梯度，或者钠或钾离子可以离子交换到玻璃中，用于含有锂或铊的掺杂剂的一部分 以产生这样的折射率梯度。
