摘要：

Concentration dependence of nonlinear refractive index n(2) in fibers heavily doped with GeO2 is studied by using the D-scan method. Good agreement with an empirical dependence established earlier with lower GeO2 concentrations by the cw dual-frequency beat signal technique is shown for GeO2 concentrations up to similar to 100 mol.%. The highest values of the nonlinear coefficient gamma at 1.25 mu m of 47.9, 57.7, and 70.9 W-1 km(-1) were obtained in fibers doped with 67, 75, and 97 mol.% GeO2, respectively.
