Research output: Contribution to journalArticlepeer-review


Spectroscopic studies of intrinsic defect centers in Yb doped silica fibers are presented. The relationship between the defect centers and photodarkening in Yb doped silica fibers is investigated. Photoluminescence from nonbridging oxygen hole center (NBOHC) and oxygen deficiency center (ODC) defects in several ytterbium-doped silica fibers are presented and analyzed. The photoluminescence spectra and temporal decays are given to determine if the Yb dopant and associated co-dopants which serve as network modifiers in the silica matrix could provide pathways whereby infrared photons could be upconverted into the UV, leading to damage in the fiber.
