Abstract: A method of preparing an organic-inorganic hybrid material is described. A M(OR)x and an organically modified Si-alkoxide having a predetermined functional group are dissolved in a first solvent and a second solvent to form a first solution and a second solution, respectively. The first solution and the second solution are then mixed and heated. As a result, the M(OR)x reacts with the organically modified Si-alkoxide to form a functionalized organic-inorganic hybrid material. Furthermore, the solid content of the functionalized organic-inorganic hybrid material is increased by transferring the same into another solvent. Therefore, a thick hybrid film is fabricated by means of the transferred functionalized organic-inorganic hybrid material.

Abstract: The reproducibility of preforms made by solution doping is significantly improved by adding an internal heat source, such as N2O, as a processing gas during the soot deposition process. The addition of the internal heat source gas results in forming a surface soot layer which exhibits a relatively uniform and consistent morphology. The improvement in the soot surface morphology results in improving the uniformity of the amount of solution dopant retained in the soot layer from preform to preform.

Abstract: A method is disclosed for fabricating a preform suitable for use in manufacturing a wide bandwidth multi-mode optical fiber. The method includes steps of employing a liquid phase spray pyrolysis technique for generating silica soot at a high rate, in combination with a non-chlorine containing liquid silica precursor and a refractory, index of refraction raising additive that overcomes the problems inherent in the use of germanium-based chemistry at typical sintering temperatures. The refractory, index of refraction raising additive is preferably comprised of a Group VB element oxide, such as a tantalum oxide. The liquid precursor is preferably comprised of a polymethylsiloxane, such as hexamethyl di-siloxane, octamethylcyclotetrasiloxane (OMCCTS), or tetramethylcyclotetrasiloxane. The step of employing a liquid phase spray pyrolysis technique includes the steps of: (a) merging at least two liquid streams, one comprised of the liquid silica precursor and another one comprised of the liquid silica precursor in combination with the additive; (b) atomizing, spraying and then combusting the merged streams to form a flame that generates silica soot that contains the additive; and (c) varying the flow rate of at least one of the streams in order to vary a concentration of the additive in the silica soot.
