摘　　要：针对常用的多路高速光脉冲复制系统可能的实现形式进行了研究,根据各种应用中所需的插入损耗、输出脉冲周期性与功率稳定性等性能要求,对多种光纤光脉冲复制结构的特点进行了分析比较。通过对各种结构的输出脉冲功率、周期性及其影响因素的理论分析,论述了使各种结构的输出脉冲优化的可能性与方法。指出了有源循环式光纤延迟脉冲复制器适合于产生重复周期准确、输出功率大的光脉冲序列。Current flber-optic pulse replication techniques for generating high-speed opt;cat pulse patterns are studied. The characteristics of different implementation of the fiber-optic pulse replicators based on different techniques are compared according to the different performance requirements of insertion loss, periodicity and power stability of the output pulses in various applications. Through the theoretical analyses of the key parameters of the replicated pulse output from these devices and their limiting factors, the feasibility and methods for further optimization of the output are presented. The optical pulse activecirculating replicator using optical amplifier is suitable for generating a sequence of pulse trains with precise periodicity and high output power.
