A method of fabricating a glass body that includes a multiplicity of constituents, at least one of which is a dopant (e.g., a rare-earth element) having a low vapor pressure (LVP) precursor includes the steps of: (a) generating an aerosol from the LVP precursor; (b) separately generating vapors of the other constituents; (c) convecting the aerosol and vapors to deposition system including a substrate; and (d) forming at least one doped layer on a surface of the substrate. In one embodiment, the method also includes filtering the aerosol so as to remove aerosol particles outside of a particular range of sizes. Also described is a unique aerosol generator that is particularly useful in generating aerosols of rare-earth dopants. Particular embodiments directed to the fabrication of Yb-doped optical fibers are described.

Apparatus and method for fabricating glass bodies using an aerosol delivery system

The present invention is directed to a process for forming composite films. The films are formed on a substrate by directing a gas containing reactant species onto the substrate. The composite film is formed from an interaction between two reactant species. At least a portion of the substrate remains within the purview of the plasma discharge while the composite film is formed on the substrate.

Process and apparatus for making composite films

The present invention is directed to a process for forming compound films that contain at least three elements. The films are formed on a substrate by directing a gas containing reactant species onto the substrate. The compound film is formed from an interaction between two reactant species. The third element is incorporated into the film as it formed. The third element is different from the other two elements that form the compound film and is hydrogen, deuterium, or oxygen. The presence of the third element enhances the properties of the compound film. At least a portion of the substrate remains within the purview of the plasma discharge while the compound film is formed on the substrate.
