Intensity-dependent refractive index due to the changes of the Er3+ concentration distribution between the ground level and upper level in Er3+ doped optical fiber has been theoretically analysized. The linit of the refractive index change at any wavelength around the gain center wavelength 1.53 μm appears when the toeal Er3+ concentration distirbutes in the upper level corresponding to the infinite pumn power.
