摘　　要：随着光通信的高速发展,精确测量高性能光调制器的高速性能的需求与日俱增。为了精确测量一个频响特性高达35GHz的光调制器,搭建了一个40GHz的器件高速性能测试系统,其中一个主要仪器为安捷伦公司生产的40GHz矢量网络分析仪。提出了一种新颖的误差去除模型,以获得光探测器的本征响应,提取结果与厂家提供的测试报告吻合。另外,根据测量得到的光调制器调制曲线,将调制器设置最佳工作点,并测量其眼图以保证调制器处在最佳工作状态。利用功率扫描法精确测量了调制器的半波电压,其他的一些重要参数也被测量。Accurate measurement of the high performance photomodulator is increasing in need. A 40 GHz high- speed measurement system has been set up to accurately measure the frequency response of a 35 GHzphotomodulator, The main instrument of the system is Agilent＇s vector network analyzer （VNA）. An error eliminate model has been derived to obtain the intrinsic response of the modulator, and the result fits well to the manufacturer report. In addition, the eye diagram of the modulator is measured when the modulator is adjusted to the best work status according to the pre-measured modulator curve. And voltage of pi phase shift is measured using power sweep method. All other important parameters are also measured and analyzed.
