Abstract

For the first time to our knowledge, we demonstrate simultaneous demodulation and slow-light delay of differential phase-shift keying (DPSK) signals at flexible bit rates using the stimulated-Brillouin-scattering-based optical filtering effect in optical fiber. Both 10 and 2.5 Gbit s DPSK signals have been demodulated and delayed with excellent performances. In the case of the 10 Gbit s DPSK signal, after demodulation the tunable delay range with error-free operation is about 50 ps , which we believe is the best result obtained for 10 Gbit s slow-light demonstrations. For the 2.5 Gbit s DPSK signal, the optimal sensitivity after demodulation is 36.5 dBm , which is comparable with the back-to-back sensitivity of a 2.5 Gbit s nonreturn-to-zero signal.
