Abstract:

Rare earth glasses have been studied with emphasis on those characteristics related to rare earth doping of optical fiber preforms for fiber sensor applications. Progress has been made in the following areas further experience with the Modified Chemical Vapor Deposition MCVD preform facility, and the establishment of an optical draw tower provides the ability to create state-of-the-art fibers with a host of novel dopants. We will continue to concentrate on fibers doped with rare earth elements by several techniques, and to continue studies of bulk formation of rare earth glasses, and to study certain aspects of second harmonic generation in rare earth doped silica based fibers.
