摘　　要：采用一种新的时钟增强方案并配合双区折射率耦合激光器实现非归零码信号的全光时钟恢复,通过数学仿真研究了此时钟恢复系统在64 Gb/s非归零码系统中的性能表现。仿真结果表明,受益于时钟增强模块的高速特性,该系统完成高速非归零码信号时钟的全光恢复能达到较好的效果。A scheme for all-optical clock recovery from non-return-to-zero(NRZ) coded data by combining a novel clock enhancement component with a two section distributed feed back(DFB) laser has been proposed, and its function and performances under 64 Gb/s NRZ data streams have been demonstrated and investigated by numerical simulation. It is shown that this system can achieve clock recovery from high-speed NRZ data with a satisfying performance.
