Abstract

This paper outlines intrinsic absorption and scattering mechanisms in chalcogenide glass fibres and how these combine to determine the waveband over which useful transmission can be achieved. Examples are presented to show how intrinsic losses can be minimised by optimising the glass composition. Extrinsic sources of loss, which include impurities and fibre imperfections, together with some of the techniques used to minimise them, are then described. Particular attention is paid to the loss mechanisms that predominate at important mid-infrared operating wavelengths, and the current best results that have been achieved with various types of chalcogenide fibre are presented.
