Abstract: The all optical pulses replicating technique for equivalent-time sampling based on active fiber loop replicator was presented.The analysis showed replication error of active fiber loop replicator caused by nonlinear gain and amplified spontaneous emission of semiconductor optical amplifier could be reduced by holding light injecting.The nonlinear errors of active fiber loop replicator and amplified spontaneous emission(ASE) noise adding in output pulses sequence were discussed.The output waveform and distribution of random error caused by ASE noise were measured too.The results show that activ fiber loop replicator is suitable to generate pulses sequence for equivalent-time sampling with waveform identity. -
