摘　　要：基于超快非线性干涉仪UNI开关具有超过40 Gbit/s的开关速度,提出一种在锁模环形腔内利用UNI开关进行时钟提取的新方案.按此方案进行实验,对40 Gbit/s伪随机信号进行时钟提取,得到了清晰稳定的时钟脉冲.与利用SOA的交叉增益调制注入锁模时钟提取方案相比,在此方案中注入到SOA的信号功率仅0.5 dBm,降低了7 dB左右,对SOA的运行更安全.Ultrafast nonlinear interferometer（UNI） is with s. A novel all-optical clock recovery scheme of extract proposed by using the UNI in injection mode-locked fiber recovered from 40 Gbit/s pseudo-random bite code series. SOA XGM in the mode-locked laser, the injection power and the SOA works more safely. the high optical switching speed ing the clock pulses laser. In experiment Compared with the c of this scheme is only from the 40 GHz of over 40 Gbit/ optical signal is clock pulses was lock recovery method using 0.5 dBm, falling by 7 dB.
