摘要
为了提高光学方法远端产生的微波信号的质量,提出了一种新的动态色散补偿方法。它只利用一个可调谐激光器(TL)和一个群时延线的斜率随波长而变化的非线性啁啾光纤布拉格光栅(FBG)。从理论深入分析了方法的原理,并且设计了所需的非线性啁啾FBG,实验验证和分析了本文方法对长为100～150km链路色散动态补偿的可行性和性能。
In order to improve the quality of the remotely generated microwave signals, we propose a novel tunable dispersion compensation approach with only a tunable laser and a nonlinearly chirped fiber Bragg grating （FBG） whose slope of the relative time delay curve varies with the wavelength. This new method is investigated theoretically, and the structure of the desired nonlinearly chirped FBG is designed to verify its feasibility of achieving dynamic dispersion compensation for links from 100 km to 150 km.
