After introducing the overlapping factors between the (pump and signal) light intensities and the erbium dopant distributions inside the fiber core, analytical solutions have been derived for rate equations appropriate to 1.48μm pumped erbium-doped amplifiers. Using the deduced expressions, important features characterizing the amplifiers have been analysed and discussed.
