摘　　要：马赫-曾德尔调制器在光控相控阵系统中有着重要作用,但是由于外界温度等环境因素的影响,会出现稳定性下降、工作点易发生漂移的现象。针对这一现象,提出了一种基于传输曲线斜率检测算法,利用STM32F103微处理器的偏置电压自动控制方案。实验结果表明,该偏压控制系统能够对马赫-曾德尔调制器的工作点进行有效调节控制,大大提高了调制器工作的稳定性。Mach-Zehnder modulators make a difference in optically controlled phased array systems.However,due to the influence of environmental factors such as outside temperature,there will be a decrease in stability and a tendency for the operating point to drift.In response to this phenomenon,a bias voltage automatic control program is proposed by using the STM32F103 microprocessor based on the slope detection algorithm.The test results show that the bias control system can effectively adjust and control the operating point of the Mach-Zehnder modulator,which greatly improves its operating stability.
