Germanium-oxide glass optical fibre prepared by VAD method

Abstract
Germanium-oxide glass optical fibre doped with antimony for transmission of the 2 to 3 μm band has been prepared by the vapour-phase axial deposition (VAD) method. An attenuation loss of 13 dB/km at 2.05 μm and 70 dB/km at 2.4 μm has been achieved.
