Large tunable delay with low distortion of 10 Gbit/s data in a slow light system based on narrow band fiber...

We describe slow light propagation of a 10 Gbit/s data stream in a narrow band fiber parametric amplifier. A large tunable delay of 10 to 60 ps with very low signal distortion has been demonstrated in a 1 km long dispersion shifted fiber. The longitudinal variation of the fiber propagation parameters was extracted from measured amplified spontaneous emission and these parameters serve to accurately predict the delayed temporal pulse shape. Simulated results suggest that the system exhibits large delays with low distortions in a wide spectral range within the OPA gain spectrum.
