Abstract

Concentration dependence of nonlinear refractive index n2 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 100mol.%. The highest values of the nonlinear coefficient γ at 1.25μm of 47.9, 57.7, and 70.9W1km1 were obtained in fibers doped with 67, 75, and 97mol.% GeO2, respectively.
