摘要

We propose and demonstrate broadband Brillouin slow light using a multiple-longitudinal-mode tunable fiber laser as Brillouin pump.A tunable broadband Brillouin pump with a tuning range from 1 520 to 1 555 nm is generated using a fiber ring laser with a semiconductor optical amplifier (SOA) as its gain medium.The pump spectrum consists of a large number of longitudinal modes separated by 6 MHz.The 3-dB bandwidth is about 11.5 GHz,and its fluctuation is less than 100 MHz within the tuning range.An 8-Gb/s data signal can be delayed by up to 83.0 ps (bit error rate ＜ 10-9) at 17-dBm pump power.
