Design and simulation of a soliton source using erbium doped fiber amplifier

Solitons are a special breed of optical pulses that can propagate through an optical fiber undistorted for tens of thousands of kilometers. The key to soliton formation is the careful balance of the opposing forces of Group Velocity Dispersion (GVD) and self-phase modulation (SPM). Resilience to Group Velocity Dispersion (GVD) and Polarization Mode Dispersion (PMD) makes optical solitons attractive for multigigabit data transmission by exploiting the ultimate capacity of the optical fibres. In this paper, a design method for soliton source is proposed and the soliton evolution from the designed source is simulated using Split Step Fourier Transform (SSFT) Method. The designed source is cost effective and highly adaptive to transmission requirement by simply varying Erbium Doped Fiber Amplifer (EDFA) parameters.
