Abstract
Buffering of a 2.5 Gb/s bit stream with non-return-to- zero format is numerically demonstrated based on stimulated- Brillouin-scattering-induced acoustic storage in an As2Se3 fiber. The storage process and the retrieval process of the bit stream are separately controlled by a "Write" pulse and a "Read" pulse. Simulation results show that output signal-to-noise ratio of 21 dB, 18 dB, 16 dB, and readout efficiency of 71%, 47%, 31% can be achieved after 5-ns, 10-ns, 15-ns storage, respectively. The "Write" and "Read" pulses are chirped Gaussian ones with single pulse energy of ~0.25 �� J and spectrum-width of ~5 GHz, which are technically achievable. Buffering of a consecutive 10- bit-long 2.5 Gb/s non-return-to-zero bit stream has also been demonstrated in the As2Se3 fiber with length of 0.5 m. This buffering method can be used for all-optical buffering in optical- communication systems.
