A numerical study on instantaneous-phase evolution of femtosecond pulses in an erbium-doped fiber amplifier
Femtosecond pulse amplification using erbium-doped fiber amplifiers (EDFAs) is a critical technique for fiber-optic communications, supercontinuum generation as well as optical frequency comb technology. When designing an ultrafast fiber amplifier, it is necessary to understand the evolution of pulse properties, such as temporal intensity and phase and frequency chirp, during pulse propagation in the gain fiber. While a lot of previous numerical research has carefully studied various pulse property variations of femtosecond pulses inside EDFAs, little work has been seen to map out the instantaneous phase evolution throughout the amplification process with all the relevant dispersion and nonlinear effects considered. Here we present our numerical results on this topic.
