Abstract:

The main research result to come from this research is the development of a new technique for the fabrication of multicomponent amorphous solids. In this method, it is possible to vary the composition of the solid during processing, thus permitting the structuring of the index of refraction in a controlled manner. It is possible to include low volatility dopants into a convective stream, and to do this in the absence of chlorine. This allows one to incorporate, in an oxide glass, many elements whose chloride is either volatile or more favored than the oxide.
