Abstract
In this work, we present the role of graphene as saturable absorber in an Erbium doped fiber laser (EDFL) for the ultrashort pulse generation. This study is important for understanding the formation and dynamic of ultrashort pulses in EDFL Cavities.To achieve this objective, we studied numerically the propagation equation in ring cavities using Ginzburg-Landau modeling and additionally, the respond the graphene as saturable absorber was incorporate in this model for the ultrashort pulse generation. As result, we investigated the monolayer graphene effects like non linear material on the noise components evolution. In fact, for the a linear absorption q 0 = 3% it was possible to have pulses formation around 2000 turns in EDFL cavity.
