摘要
借助半导体光放大器(SOA,Semiconductor Optical Amplifier)动态噪声模型结合蒙特卡罗方法对有源光纤环脉冲复制器的复制误差特性进行了研究.对复制误差与环内衰减器衰减、SOA偏置电流、环内注入直流光波长与被复制脉冲幅度等各项参数之间的关系进行了研究.仿真结果表明,较小的环内衰减与较大的偏置电流有助于抑制复制误差,而环内注入直流光波长则应选择较长的波长.通过这些仿真结果探讨了减小复制误差的手段.根据分析结果建立了实验系统,验证了有源光纤环脉冲复制器的低失真复制特性.实验证明有源光纤环脉冲复制器可以对脉冲进行有效的低失真复制.
The replicating errors of active fiber loop replicator （AFLR） were discussed by using a dynamic model of noisy of semiconductor optical amplifier（SOA） and Monte-Carlo method. The replicating error changing due to the attenuation in fiber loop, the bias current of SOA, wavelength of assist light and peak power of replicated pulse were analyzed. The results show that low attenuation and middle bias current are preferred to achieve low replicating error. And the assist light should choose long wavelength. The methods to minimize replicating error were given by using numerical analysis. An experimental study about replicating performance of AFLR was presented at end. Experiment shows that AFLR can replicate pulse with low error.
