Abstract

PURPOSE:To obtain an easily handleable glass fiber having a large number of apertures by cladding chalcogenide glass as a core with plastics at the outside. CONSTITUTION:Starting materials for Ge, Se and P are packed in a quartz glass tube 2. After sealing and evacuating the tube 2, the materials are melted and air-cooled to form a Ge3Se9P glass rod 3. This rod 3 is covered with a pipe 8 of ''Teflon FEP '' or ''Teflon PFA '', and while feeding an inert gas 1, the tip of the covered rod is heated with a platinum heater 4. The glass and the Teflon pipe are then drawn simultaneously to obtain a Teflon clad Ge3Se9P glass fiber. The drawing speed is regulated with guide rollers 7.
