Applications Of Chalcogenide Glass Optical Fibres

Chalcogenide-glass fibres based on sulfide, selenide and rare-earth-doped compositions are being actively pursued worldwide. Great strides have been made in reducing optical losses using improved chemical purification techniques,bur further improvements are needed in both purification and fiberisation technology to attain the theoretical optical losses. Despite this, chalcogenide-glass fibre are enabling numerous applications that include laser power delivery, chemical sensing, and imaging, scanning near field microscopy, IR sources/lasers, amplifiers and optical switches.
