Abstract
The problem of excess loss in single-mode germanosilicate optical fibe rs with GeO2 content 20 to 35 mol% is experimentally studied. Excess l oss in such fibers is due to the drawing-induced defects, UV absorptio n tail and scattering. It is sensitive to drawing conditions and to co doping with F and P. Codoping with P results in additional loss presum ably caused by P-related drawing-induced defects. Codoping with F dimi nishes the excess loss presumably by smoothing the inhomogeneous distr ibution of GeO2 in SiO2-GeO2 glass. (C) 1997 Academic Press.
