摘　　要：报道了一种全部由 10GHz带宽的元件构成的、用于时钟提取的双环注入锁模光纤激光器 这种装置集光电振荡器 (OEO)与注入锁模光纤激光器的优点于一体 ,利用它不仅从恶化的数据信号中实现了 10Gb/s的位时钟提取 ,在采用了光电振荡器的分频、锁模光纤激光器的有理谐波锁模以及F P梳状滤波器的频率倍乘技术以后 ,还从 2 0Gb/s和 4 0Gb/s的恶化信号中提取出了位时钟A novel clock recovery scheme using two ring injection mode locked fiber ring laser based on all 10 GHz bandwidth components was demonstrated. With this scheme, the clock with low timing jitter was obtained from a degraded 10Gb/s optical data stream. Optical clock recovery was also achieved from degraded 20Gb/s and 40 Gb/s optical data trains when the clock division technique in the opto electronic oscillator (OEO), the rational harmonic mode locking technique in the fiber ring laser and repetition rate multiplying technique using F P comb like filter were applied. No pattern effect was observed in these experiments.
