摘要: 为了提高基于SOA-MZI结构的全光异或门的输出消光比，优化系统性能，将SOA和HNLF相结合，在光通信系统设计软件OptiSystem7.0仿真平台上搭建了基于SOA-MZI的全光异或仿真实验模型，对两路40 Gbit/s的RZ码数据信号进行了全光异或仿真实验。利用HNLF的非线性效应设计了一种优化结构对基于SOA-MZI的全光异或输出信号进行优化，并对优化前后的信号时域波形图和系统眼图进行了比较分析，通过多次反复实验得到一组最佳的系统参数，使得基于SOA-MZI的全光异或门的输出消光比从10 dB提高到约28 dB。实验结果表明：常规的基于SOA-MZI的全光异或门由于相消干涉不彻底造成输出消光比较低，而经过优化，很好地解决了这种问题，提高了异或输出消光比，优化了系统性能。Abstract: In order to improve the output extinction ratio of all-optical XOR gates based on SOA-MZI structure, and optimize the performance of system, the SOA was combined with the HNLF, and the all-optical XOR simulation experiment model based on SOA-MZI was built on the simulation platform of optical communication system designing software OptiSystem7.0, and the all-optical XOR simulation experiment was carried out to two RZ format data signals at 40 Gbit/s. In addition, the all-optical XOR out signals based on SOA-MZI was optimized by a kind of optimization structure which was designed by using the nonlinear effects of HNLF, and the signal waveform diagram of time domain and eye diagram of system before and after optimizing were analyzed and compared. Through a lot of repeated experiments, the optimal system parameters were obtained to make the extinction ratio of all-optical XOR gate based on SOA-MZI be improved from 10 dB to about 28 dB. The experiment results show that the output extinction ratio of conventional all-optical XOR gate based on SOA-MZI is lower because of the incomplete destructive interference, but this problem is solved perfectly by optimizing, the output extinction ratio is improved, and the system performance is optimized.
