Stimulated Brillouin scattering in optical fibers is carefully reassessed for the case of distributed optical gain (achievable in optical fibers lightly doped with rare-earth ions) instead of the usual loss. The effects of gain and amplified spontaneous emission on the threshold power are discussed, together with treatments of the effects of amplification on the line-narrowing process normally associated with stimulated Brillouin scattering in a lossy medium and the appearance of strong higher-order Stokes waves. The implications for erbium-doped fiber amplifier systems are explored.
