摘要
对光纤中简并四波混频(DFWM)耦合波方程进行数值求解,通过分析发现: 泵浦光功率的增大会导致泵浦光与反斯托克斯光之间能量交换周期减小。阐述了优化光纤中DFWM实现全光信号幅度整形的机理。在此基础上设计了一个优化的全光信号幅度整形系统,并进行了系统仿真,结果表明: 通过再生系统后,信号的消光比从9.46 dB提升到30.40 dB,品质因子从15.95提升到了180.40。
Abstract
The paper presents the solutions of coupled-waves equations of degenerate four-wave mixing (DFWM) numerically. The results show that the power increase of pump wave can decrease the period of energy interchange of pump and anti-Stokes waves, and the power transfer relationship of pump and anti-Stokes waves in specific distances can be used for all-optical signal amplitude reshaping. The all-optical signal amplitude reshaping principle is explained from this point of view, and an all-optical signal reshaping system is designed accordingly. The system is tested through the eye diagrams of input and output signals, extinction ratio (ER) and Q-factor by simulating. It improves the ER and Q-factor from 9.46 dB to 30.4 dB and 15.95 to 180.4 respectively.
