Abstract
Demonstration is provided for the generation of high quality replicated optical pulse trains, from a single pulse. This uses the storage capability of an electro-optically switched recirculating fibre loop. For better understanding, the first step involves the development of general purpose derivations related to the evolution of the noise with near-unity loop gains. This is a basic tool to evaluate the propagation of the noise and the temporal evolution of the signal to noise ratio during the replication process. In a second step, the comparison of theoretical and experimental results will be shown to evidence good agreement, up to more than 1000 replica. Finally, experiments are performed on synchronised gain-switching inside the loop to help optimise the dynamic range of replication at the output of the system.
