Abstract
The amplification of an ultrabroad bandwidth pulse in an Erbium-doped fiber amplifier in the case where the spectral bandwidth of pulse is comparable to the gain bandwidth of the amplifier is investigated. Based on the numerical simulation of a modified nonlinear Schrödinger equation, it is shown that the amplifier limits the efficiency of amplification. However, the limitation can be minimized by choosing the corresponding optimal fiber length for different gain bandwidths. In addition, the effect of gain bandwidth on the amplification of a soliton with initial chirp depends on the sign of the chirp.
