Mach-Zehnder型电光强度调制器中残余啁啾的表征与补偿
Characterization and Compensation of the Residual Chirp in a Mach-Zehnder-Type Electro-Optical Intensity Modulator
摘要：
我们利用各种技术来表征基于光纤的马赫-曾德尔电光强度调制器的剩余相位调制。外差技术用于直接测量由于给定的强度变化而引起的相位变化，从而确定器件的啁啾参数。该啁啾参数也通过检查正弦幅度调制的边带比来测量。最后，通过外差信号测量纳秒时间尺度上的强度脉冲引起的频率啁啾。我们表明，这种啁啾可以在很大程度上补偿一个单独的相位调制器。啁啾参数的各种测量结果是合理的协议。
英文摘要：
We utilize various techniques to characterize the residual phase modulation of a fiber-based Mach-Zehnder electro-optical intensity modulator. A heterodyne technique is used to directly measure the phase change due to a given change in intensity, thereby determining the chirp parameter of the device. This chirp parameter is also measured by examining the ratio of sidebands for sinusoidal amplitude modulation. Finally, the frequency chirp caused by an intensity pulse on the nanosecond time scale is measured via the heterodyne signal. We show that this chirp can be largely compensated with a separate phase modulator. The various measurements of the chirp parameter are in reasonable agreement.
