Slow light due to stimulated Brillouin scattering in fibers is a promising technique to realize all-optical data storage and synchronization. For delaying high-speed data, we demonstrate an approach to solve the problem of narrowband Brillouin gain by phase-modulating the Brillouin pump. The bit rate of the phase-modulating signal determines the Brillouin gain bandwidth. A 1.25-Gb/s nonreturn-to-zero...
We demonstrate a new in-band OSNR monitoring scheme using RF spectral analysis of gated framing-signal of synchronous traffic. The proposed technique is simple and robust to fiber-nonlinearity induced polarization rotation in WDM systems
