Characterizing Trace Metal Impurities in Optical Waveguide Materials Using X-Ray Absorption
Published online by Cambridge University Press: 10 February 2011
Abstract
X-ray absorption measurements are described for identifying metal impurities insilica preforms, the rod-like starting materials from which hair-like optical fibers are drawn.The results demonstrate the effectiveness of this approach as a non-destructive,quantitative, element-selective, position-sensitive, and chemical-state-specific means forcharacterizing transition metals in the concentration regime of parts per billion.
