Abstract

The stimulated Brillouin backscatter is reduced by non-linear effects, such as self-phase modulation or cross-phase modulation. Due to the cross-phase modulation, a bandwidth spread and, as result thereof, a reduction of the stimulated Brillouin backscatter is also achieved by supplying at least one amplitude-modulated pump signal.
