Stimulated Brillouin scattering excited by two pump waves in single-mode fibers

Stimulated Brillouin scattering (SBS), excited by two pump waves in single-mode fibers, is investigated both theoretically and experimentally. Steady-state calculations, supported by experimental results, show that the SBS gain depends on the ratio of the pump coherence length to the characteristic gain length of the SBS as well as on the ratio of the frequency separation between the two pump waves to the SBS linewidth. These dependences are fully analyzed by following the evolution of the pressure wave that is generated by the SBS interaction. The competition between four-wave mixing and SBS is also considered.
