在O-RPR(optlcal resltient packet ring)光弹性分组环的基础上分析了在双环耦合全光缓存器这一基于半导体光放大器(SOA)的光控器件中要顺利实现数据的读写控制对光控制层功率提出的要求及其影响因素,讨论了由于信号光脉冲形状不是理想方波而造成的啁啾及脉冲压缩现象,分析了控制光功率波动及其信噪比对输出数据造成的影响.得到的结论对其他基于SOA的光控器件同样具有借鉴意义.
On the basis of optical resilient packet ring ( O-RPR), this paper analyzes the control optical power needed for dual loop optical buffer (DLOB) to achieves 'write-read' successfully, and discusses the influencing factors on this power. Then we discuss the pulse compression and chirp caused by the signal pulse not being ideally square, and analyze the influence of power fluctuation and signal-to-noise ratio(SNR) of control light on output data.
