Abstract :
An analysis based on numerical simulations of the optimum erbium-doped fibre (EDF) design for use in L-band amplifiers is presented. The efficiency of the EDF is found to peak at a cutoff wavelength of ~1100 nm, when operated in an L-band amplifier. The gain per length increases monotonously with the cutoff wavelength independent of numerical aperture
