Abstract
A perturbation analysis of stimulated backward Brillouin scattering (SBBS) in single mode optical fibers is presented. The nonlinear interaction between the pump and Stokes waves, optical loss and Bragg diffraction have been all considered. The analytic expressions of the threshold, output Stokes intensity, efficiency for the SBBS fiber amplifiers and lasers are derived. We show that the stronger Bragg diffraction will increase the Brillouin diffraction efficiency and decrease the threshold of SBBS. Effects of acoustic guidance conditions of optical fibers on the above SBBS parameters will be discussed.
