ABSTRACT
The paper provides simple expressions for the dopant concentrations that optimize the bandwidth of a fiber at a number of wavelengths. The solution is related to Olshanky’s multiple α profiles. Numerical application is made for germania, fluor and phosphorus doping at wavelengths where the losses are small. The effect of a free parameter on the fiber ∆ and its bandwidth is outlined.
