We report on the demonstration of optical fibres based on the Ga:La:S system. Coreclad structures have now been fabricated by the rod and tube method and pulled into lengths over 200 metres. Transmission over the wavelength range 1.0 to 6.5 microns, with fibre loss approaching the absorption and scattering level of the bulk glass is obtained, opening the possibility of new fibre device applications of this promising glass host. Progress towards low-loss single-mode fibre will be outlined along with applications a optical fibre amplifiers operating at 1.3 microns and fibre lasers at wavelengths in the 3-5 micron region.
