Abstract

Chalcogenide glass fibres have been developed for transmission in the 8-12 µm waveband. The bulk properties of a range of selenide and telluride glasses have been studied and compositions chosen to optimise transmission and glass stability. The role of major impurities and the procedures used to minimise them are described. Selected compositions have been drawn into long lengths of polymer coated fibre with diameters controlled accurately up to 500 µm. Current fibres transmit with losses of 5-10 dB m^-1 in the 8-12 µm waveband. Approximately 4 dB m^-1 of this loss is attributable to scattering. Mechanical testing has shown that fibre strength is determined by internal defects. Their elimination should enable fibres to sustain bend radii of the order of one centimetre, and at the same time should reduce minimum losses to below 1 dB m^-1.
