N2 - Despite the use of stimulated Brillouin scattering in amplifying the input signal, this scattering can cause undesirable effects in data transport or increase the power of fiber lasers. In this paper, a method based on the application of periodic stress is presented to address this undesirable effect. Based on this, by modulating the refractive index of the optical fiber, at 100 kHz, the intensity of the Stokes spectrum was reduced by the stimulated Brillouin scattering, which was twice as large.
