Abstract

In this paper, we first define a complex refractive index profile for the pumped Erbium Doped Fiber which depends on radial distance, pump and signal powers and Er-doping profile in order to obtain modal gain/loss of the propagating signal/pump power by a Rayleigh Ritz Variational analysis. This provides a novel way of looking at the gain characteristics of EDFAs. Next, we use this to estimate the total signal gain in fiber lengths for given input pump power levels.
