Abstract
We numerically investigate the performance improvement and its limitations using super-Gaussian filtered incoherent pumping in Stimulated Brillouin Scattering (SBS) slow light systems, especially for 2.5-Gb/s return-to-zero (RZ) OOK data streams. As compared to regular Gaussian filtering schemes, super-Gaussian filters can reduce the signal broadening without sacrificing the generated delay. On the other hand, although the figure-of-merits (FOM) in terms of the normalized delay and signal Q-factor products can be improved as well, additional sub-pulses may appear and subsequently the curve of FOM versus slow-light bandwidth exhibits a fluctuated behavior.
