ABSTRACT:
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 comprises 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.
