Abstract :
The generation of alternate multiwavelength pulse trains in an actively mode-locked erbium-doped fiber laser containing an unbalanced Mach-Zehnder interferometer is analyzed using numerical simulations and a theoretical Gaussian pulse analysis. The results obtained allow the interpretation of recent experimental results reporting multiwavelength pulse laser operation and provide a clear physical description of the operation of the multiwavelength laser. Furthermore, the analysis and modeling also provide guidelines for experimental design.
