Processing and characterization of bulk chalcogenide glasses used for waveguide applications
Chalcogenide glasses (ChG) are of interest due to their optical and electronic properties for use in waveguide applications. To assess expected uniformity, in films deposited from bulk glass starting materials, the extent of parent bulk glass property variation was evaluated. Resulting structural and optical properties of melt-derived ChG's were investigated using X-ray diffraction (XRD), Raman spectroscopy, differential thermal analysis and spectrophotometric analysis. The influence of melt size, purification, and other melting conditions on sample homogeneity were quantified and within-melt property variation of bulk glass samples was found to be less than 5% for all parameters examined.
