    Abstract: PROBLEM TO BE SOLVED: To provide a durable particle generator capable of high temperature particle synthesis and an apparatus capable of clean high temperature synthesis of small particles and nanoparticles.SOLUTION: In the particle generation apparatus, the apparatus includes at least one vessel comprising: (a) an interior space for accommodating the passage of reactant material therethrough; (b) at least one susceptor capable of generating heat when acted upon by energy and being disposed such that a temperature sufficient to heat the reactant material within a predetermined range is achieved within the interior space; and (c) a heat-transmitting barrier layer interposed between the susceptor and the interior space for isolating the susceptor from the reactant material. The particle generator is configured as to minimize susceptor degradation associated with harsh reaction conditions.

    Abstract: The present invention is directed to a process for forming a preform suitable for consolidation to a glass blank for producing an optical waveguide fiber. The preform comprises a core portion and an inner cladding layer surrounding the core portion and contains SiO2 and TiO2. A portion of the TiO2 in the preform is in a crystalline form that is predominantly rutile. In addition to SiO2 and TiO2, the preform contains an additive compound that is preferentially sacrificed instead of TiO2 when the preform is consolidated. The process includes oxidizing Si and Ti containing compounds as well as a precursor of the additive compound to form SiO2, TiO2, and the additive compound. The preform containing these materials is then formed. In addition, the preform can be converted to a glass blank by consolidation of the preform.

    Abstract: Suppression of stimulated Brillouin scattering (SBS) by broadening the energy spectrum of participating SBS photons and/or phonons is achieved in an optical fiber having a core with both radially nonuniform viscosity and CTE profiles provided by alternating layers of glass modifying dopants such as phosphorous and fluorine. The nonuniform thermal expansion and viscosity profiles impart a residual, permanent, nonuniform stress in the fiber. The SBS suppressing effect provided by the nonuniform stress can be controlled and enhanced by applying a uniform or nonuniform tensile force to the fiber as it is being drawn. A preform for the fiber is also disclosed.

    Abstract: A method for making silicon oxynitride comprising providing a vaporous gas stream of a compound selected from the group consisting of silazanes and siloxazanes. An enclosed, heated reaction site is also provided. The vaporous gas stream is delivered to the enclosed, heated reaction site in which the levels of oxygen are strictly controlled to promote the formation of silicon oxynitride particles.
