Adjusting the Brillouin spectrum in optical fibers for slow and fast
... If the bandwidth of the gain is narrow the time delay is high but the pulses experience a strong distortion which leads to a broadening. The natural Brillouin bandwidth would result in data rates which could be delayed of only 15Mbit/s. To enhance the bandwidth the gain can be broadened by a direct ...
