摘　　要： 对4×10GHz光时分复用(OTDM)系统中,基于LiNbO3调制器的注入光电混合振荡器的时钟提取方法进行了实验验证,提取的时钟抖动小于0.5ps。从实验上分析了入射光功率对时钟信号的影响。同时利用提取的时钟实现了基于电吸收调制(EAM)晶体的各个信道的解复用,解复用信号基本无邻道串扰。 Clock recovery using the injected optoelectronic hybrid oscillator based on LiNbO3 modulator was described and tested in 4×10 GHz optical time division multiplexing systems(OTDM).The resuts show that the time jitter of extracted clock is less than 0.5 ps.The influence of input optical power on extracted clock was analyzed experimentally.Simultaneously each channel was demultiplexed with EAM(electrical absorb.modulat.) under the driving of the extracted clock,and noncrosstalks are existent for the demultiplexing.
