有源光纤环脉冲复制器的噪声特性研究

Study of noise distribution of active fiber loop replicator

借助半导体光放大器(Semiconductor optical amplifier,SOA)静态模型分析了有源光纤环脉冲复制器的输出放大自发辐射(Amplified spontaneous emission,ASE)噪声功率特性与环内SOA偏置电流及环内注入直流光功率之间的关系,并对环输出噪声分布的形态进行了仿真分析。用较少的实测数据点,使用插值方法对原有噪声曲线进行了快速重构。实验研究了其重构误差分布。

A numerical model of active fiber loop replicator （AFLR） based on a steady-state model of semiconductor optical arnplifier（SOA） is used to analyze the output amplified spontaneous emission（ASE） power distribution when the bias current and input power of active finer loop replicator（AFLR） is changed. An analytical analysis of output noise performance of the systern is carried out. An interpolation method to recover original noise distribution using measured data is validated, and the recovery error is measured by an experimental way.
