| 摘 要： | 为了全光处理具有固定功率差异光信号,本文在详细分析非线性光纤环形镜(NOLM)受不同泵浦作用时输出特点的基础上,设计了将二元功率光信号进行幅度直接均衡的方案.利用光子学仿真软件进行了数值实验,结果显示二元信号经幅度均衡后的输出功率由均衡器输出级探测波功率直接确定,输出脉冲无波长改变,且幅度抖动小.输出脉冲无基座表明该方...

| Abstract: | For all-optically processing the optical signal with a fixed power difference,the scheme for directly balancing two-level power optical signal is designed on the basis of a detailed analysis about the output characteristics of the nonlinear optical loop mirror（NOLM） by differently pumped.The numerical experiments are executed through using photonics simulation software.The results show that the output power of two-level signals is directly defined by the input power of continue probe wave at the output stage of the equalizer after equalizing amplitude.The wavelength of the output pulse is not changed,and the amplitude jitter is little.The Output pulse without pedestal indicates that this scheme has the ability to eliminate pulse pedestal.So,the scheme can be used for eliminating noise and the impact of fiber dispersion within the NOLM in all-optically processing signal. |
