We propose a novel doped fiber structure, for the enhancement of power conversion efficiency (PCE) in an L-band erbium-doped fiber amplifier. With proper adjustment of the doping profiles for the reduction of pump absorption rate, it becomes possible to optimize the pump evolution inside the doped fiber so as to improve the PCE, while suppressing the development of pump-depleting detrimental amplified spontaneous emission. Exemplary analysis shows significant enhancement in the saturation output power of more than 58.5%, when compared to conventional C-band erbium-doped fiber.
