Abstract

The stimulated Brillouin scattering (SBS) of coherent light pulses launched into an erbium-doped fiber (EDF) is reported. In a 50 m EDF, the SBS peak power reaches about 40 dBm for input powers higher than the threshold power of about 6 dBm. SBS and its amplification in an erbium-doped fiber amplifier (EDFA) result in the deformation of a forward-amplified pulse due to the Brillouin power conversion and deterioration of the EDFA population inversion. It is also shown that very short EDF is effective in suppressing the SBS.<>
