Abstract

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