✦ Synopsis

We present a nondestructive method that allows the spectral birefringence characterization of single-mode erbium-doped fibers within the amplification band. Using the same optical set up and the predicted polarization eigenmodes, the quality of the results has been verified. The results obtained for three commercial erbium-doped fibers with different erbium concentrations are shown. For two of them, the values measured for the elliptical birefringence shift, for different signal wavelengths, from having a dominant circular component to exhibit a dominant linear component.

The problem of excess loss in single-mode germanosilicate optical fibers with GeO content 20 to 35 mol% is experimentally 2 studied. Excess loss in such fibers is due to the drawing-induced defects, UV absorption tail and scattering. It is sensitive to drawing conditions and to codoping with F and P
