Paper Abstract

The performance of systems employing Brillouin Dynamic Gratings may suffer from noise generated by the spontaneous Brillouin processes. It is experimentally demonstrated that spontaneous emissions, accompanying the signal of interest, contain not only the probe spontaneous Brillouin backscattering but also a significant contribution from the co-propagating writing pump. For a strong enough writing pump and even moderate probe power levels, the observed noise is dominated by the pump, exhibiting an average backscattered power more than 30 dB stronger than that of the probe alone.
