摘　　要：介绍了一种用于A/D转换的120GS/s光采样时钟。讨论了生成这种采样时钟的方法,以及一种以其为基础的全光示波器。用Matlab实现飞秒激光脉冲谱分割以及复用的仿真,并进一步说明了用生成的光脉冲序列进行采样时需要考虑的问题。将Optisystem的仿真结果与Matlab的结果进行对比,并用Matlab计算的衰减率结果对Optisystem生成的采样光序列接行了优化。A 120 GS/s optical sampling clock in A/D converter is introduced,and the method of generating such a sampling clock and an optical oscilloscope based on the sampling clock are demonstrated.Matlab simulation is used to realize the division and multiplexing of femtosecond lasers’ spectrum,and the problems in using the generated optical sequence to sample are discussed.The simulation result of Matlab is compared with that of Optisystem,and finally the attenuation rate of the optical sampling sequence calculated by Matlab is used to optimize the sequence simulated by Optisystem.
