Abstract

A theoretical model for quantifying the pulse distortion introduced by the stimulated-Brillouin-scattering (SBS)-induced (equivalent) dispersion in a linear Brillouin slow-light system is presented. Based on this model, a linear Brillouin slow-light system employing fast-light propagation for dispersion compensation is analyzed. The results show that the elimination of gain-nonuniformity-induced equivalent group-velocity dispersion can be achieved with the sacrifice of introducing much larger high-order (equivalent) dispersion effects. It is also shown that the simultaneous cancellation of gain-nonuniformity-induced equivalent group-velocity dispersion and third-order dispersion as presented in a recent article is impossible.
