摘要
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10 Gbit/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。
Abstract
To compensate the drift of fiber loop length in fiber-optic parametric oscillator (FOPO), a novel feedback control scheme based on four-wave-mixing idler power is put forward. The feasibility of this scheme is confirmed by the clock extraction experiments for 10 Gbit/s optical return to zero (RZ) signal, and the normalized phase and amplitude jitter of less than 0.015 and 0.06 can be achieved under long-time stable operating condition. Thus, the scheme proposed in this paper is of practical applicability for the FOPO′s stability of oscillation.
