Paper Abstract

At Southampton, our work has focused on gallium lanthanum glass and fiber, for both active and passive applications. As part of our ongoing program, optical, thermal and mechanical properties of these glasses are under study. In parallel with this, fiber drawing is being refined in a quest for practical fibers. Over the past year, improvements have been made in understanding and eliminating the sources of loss in these glasses. In this paper, we describe the current specifications of fibers based on this material group. Recent progress in several applications, in particular those extending into the IR will be reported and the prospects for a future generation of sulphide-fiber based devices examined.
