为了补偿光纤参量振荡器光纤环的长度漂移,提出一种基于四波混频闲频光功率的反馈控制方案。通过10Gbit/s归零(RZ)光信号的时钟提取实验证实了该方案的可行性,所提取时钟信号的归一化相位抖动与幅度抖动分别在0.015与0.06以下,并可长时间稳定工作,因此该方案具有很强的实用性。 In order to compensate the length drift of optical fiber parametric oscillator fiber loop, a feedback control scheme based on four-wave mixing idle-frequency optical power is proposed. The feasibility of this scheme is verified by the clock extraction experiment of 10Gbit / s zeroing (RZ) optical signal. The normalized phase jitter and amplitude jitter of the extracted clock signal are below 0.015 and 0.06, respectively, and can work stably for a long time. Therefore, the program has strong practicality.
