Paper Abstract

Dispersion effect in stimulated Brillouin scattering (SBS) slow light is studied to compensate the pulse distortion using SBS - dispersion decreasing fiber (SBS-DDF). SBS-DDF has the feature of the dispersion increasing and effective area decreasing, hence intensity increasing along the fiber. This increased intensity is used to balance the intensity decreasing of the pump beam from pump and probe interaction in Brillouin medium at the Brillouin frequency and fiber attenuation. The same principle is applied to the counter propagating Stokes wave, that decreased intensity due to the effective core area increasing is used to eliminate Stokes beam saturation through Brillouin loss interaction. A minimum pulse distortion with high delay of 1.8ns over 2ns pulse is achieved.
