Studies on error of active optical pulse replicator

The replicating errors of active fiber loop replicator (AFLR) were discussed by using a dynamic model of noisy of semiconductor optical amplifier (SOA) and Monte-Carlo method. The replicating error changing due to the attenuation in fiber loop, the bias current of SOA, wavelength of assist light and peak power of replicated pulse were analyzed. The results show that low attenuation and middle bias current are preferred to achieve low replicating error. And the assist light should choose long wavelength. The methods to minimize replicating error were given by using numerical analysis. An experimental study about replicating performance of AFLR was presented at end. Experiment shows that AFLR can replicate pulse with low error.
