Extruding chalcogenide glass for optical fibre

ChAMP has demonstrated for the first time fabrication of a core-clad GLS-Se glass-based optical fibre using extrusion. For initial demonstration two glass compositions similar in thermal and mechanical characteristics were chosen, with only a 5wt% difference of Ga2Se3 between core … Continue reading
