| 摘 要： | 为了研究放大反馈激光器全光时钟提取的性能,采用单边带相位噪声功率谱积分的方法,对40Gbit/s无恶化信号和噪声恶化信号分别进行了时钟提取实验,计算了所提取时钟的时间抖动。同时还测量了放大反馈激光器的锁定范围。通过实验取得了恶化前后所提取时钟的时间抖动分别为130fs和150fs,放大反馈激光器的锁定范围为234MHz。结果表明,基于放大反馈激光器的全光时钟提取方案对噪声恶化具有较强的容忍度,而且具有较宽的锁定范围。这一结果对于全光时钟提取技术的进一步发展具有重要意义。

| Abstract: | In order to investigate the performance of all-optical clock extraction using an amplified feedback laser, the method of single sideband phase noise intensity integration was adopted. The clock extraction from not-degraded and noise-degraded 40Gbit/s signals was experimentally demonstrated and timing jitter of the extracted clock was calculated. Besides, the locking range of amplified feedback laser was measured. As a result, the clock extracted from the not-degraded and noise-degraded signal with timing jitter of 130fs and 150fs were obtained respectively. The measured locking range of amplified feedback laser was 234MHz. The experimental results show that the amplified feedback laser-based all-optical clock extraction has a high tolerance to the noise degradation and a wide locking range. The results are important for the further development of all-optical clock extraction technology. |
