Paper Abstract

The impact of silica glass structure on the transmission properties of Ge-doped single-mode optical fibers was studied. Test fibers with significantly different fictive temperatures (Tf) and residual stresses were drawn by varying cooling rate. Tensile or compressive residual stresses were achieved in core of the fibers. The results show that: (1) Both residual stress and Tf have an impact to the transmission properties, in particular, the stress in core. (2) A greater complexity was found in the relationship between transmission properties and glass structure than has been shown earlier. E.g. Rayleigh scattering was found to decrease and loss imperfection factor to increase with increasing Tf within one of the fiber series. Thus Tf can not alone be used to characterize the fiber glass structure. (3)Rayleigh scattering is dependent on both Tf and residual stress, in particular on core stress and probably on the structure of core glass. A relatively low Rayleigh scattering was found in fibers with Tf as high as 1600°C. (4) Zero dispersion- and cut-off wavelengths are modified by residual stress.
