摘 要：高速光电子器件是大容量光通信系统和宽带微波光子系统的基础，器件的高频响应测量对于实现电光和光电转换具有重要的意义。本文基于光外差理论提出了移频外差方法用于实现光域光谱到电域电谱的映射，在电域获得光谱和电谱的联合分析。实验中，通过配置电域谱线的频率关系，利用移频外差将所需光载波和边带从光域映射到电域，实现了高速马赫曾德尔调制器、相位调制器和光电探测器的自校准高频测试，获得了马赫曾德尔调制器的调制系数、半波电压和啁啾参数、相位调制器的调制系数、半波电压以及光电探测器的响应度等多种高频参数。结果表明，本文方法具有宽频段、高分辨、多参数、自校准测试的优点。

Title：Self-Calibrated High-frequency Analysis of High-Speed Optoelectronic Devices by Frequency-shifted Heterodyne
Abstract：High-speed optoelectronic devices are key elements for large-capacity optical fiber communication systems and wideband microwave photonic systems, in which the high-frequency characterization of optoelectronic devices is of importance for the precise signal conversion between optical domain and electrical domain. In this paper, we proposed a frequency-shifted heterodyne method based on optical heterodyne theory for the mapping optical domain spectrum to electrical domain spectrum, in order to obtain the joint analysis of optical spectrum and electrical spectrum in the electrical domain. In the experimental demonstration, self-calibrated high-frequency measurements of Mach-Zehnder modulators, phase modulators and photodetectors are successfully operated through carefully choosing the frequency relationship between the desired mapped electrical spectrum lines, and most parameters, such as modulation index, half-wave voltages, chirp and responsivity are extracted for the three kind devices. Results indicate that our method is helpful for the wideband, high-resolution, multiparameter, self-calibration measurement of high-speed optoelectronic devices.
