【摘要】 为了研究向全光等效时间采样系统提供被采样一致脉冲序列的技术,讨论了使用有源光纤环脉冲复制器进行脉冲复制的方法。分析了利用环内注入直流光实现对复制器非线性增益与放大自发辐射噪声所导致误差的抑制。通过实验得到了复制器误差随环内注入直流光的变化趋势、复制器复制稳定性和误差分布的测量结果。结果表明,利用有源光纤环脉冲复制器可以有效地产生被采样等效时间周期脉冲序列。更多还原

【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.更多还原
