Abstract

A calibration-free and three-in-one electro-optic frequency sweeping-based method is proposed for the electrical spectra and frequency response characterization of mode-locked fiber laser (MLFL) MLFL, intensity modulators (IMs), and photodetectors (PDs) with a shared measurement scheme. By carefully setting the frequency relationship between the swept frequency, the extra influence from other assisted devices besides device under test (DUT) is fully cancelled out by analyzing the power ratio between the single-tone driving signal and electrical signals of the MLFL after photodetection. Moreover, the wideband requirement of the assistant devices is reduced by half to that of the DUT in the cases of the MLFL, IM, and PD measurement, respectively. The microwave characterization of the MLFL, IM and PD are experimentally extracted with the proposed method and the measured results are compared to those obtained with the traditional electro-optic frequency sweeping method to check the consistency and accuracy.

模式锁定光纤激光器的电光谱特性及在高速光电器件测量中的应用

本文提出了一种基于电光扫频的免校准三合一方法，通过共享测量方案对锁模光纤激光器（MLFL）、强度调制器（IM）和光电探测器（PD）进行电光谱和频率响应表征。通过仔细设置扫频之间的频率关系，分析单音驱动信号与光电检测后 MLFL 电信号之间的功率比，可以完全消除除被测设备（DUT）之外的其他辅助设备的额外影响。此外，在测量 MLFL、IM 和 PD 时，对辅助器件的宽带要求分别比 DUT 降低了一半。利用所提出的方法通过实验提取了 MLFL、IM 和 PD 的微波特性，并将测量结果与传统的电光扫频方法进行了比较，以检验其一致性和准确性。

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
