Abstract
Buried waveguiding planar modes of well-defined profiles were observed in samples undergoing simultaneous Ti indiffusion and Li outdiffusion in a water vapor atmosphere. Each of these modes was distinctly excit ed by end-fire fiber coupling and suffered no loss by metal loading. A n index profile which fits the mode shapes measured, and a mechanism i s suggested based on the influence of a Ti-rich layer compound on the Li outdiffusion process.
