Fiber-Based Techniques to Suppress Stimulated Brillouin Scattering

Stimulated Brillouin scattering (SBS) is the major factor that limits maximum optical fiber output power in narrow linewidth applications, which include important fields such as passive networks (PONs), high-power amplifiers, and lasers. Great efforts have been dedicated to suppressing SBS effect increasing power. This paper focuses on key fiber-based techniques suppress SBS. These take advantages of properties fibers. We present how these (electric modes, acoustic material properties) could be utilized The are divided into transverse design, longitudinal variant external perturbations (strain temperature) Transverse design mechanism electro-acoustic interaction. Large effective area tailoring discussed. Longitudinal considers nonlinear interaction along propagation distance, various related presented. External fibers emphasize static modify effect.
