摘　　要：通过数值模拟研究了非线性元件的偏移量对ＴＨｚ光学非对称解复用器开关窗口的影响，结果表明，ＴＨｚ光学非对称解复用器的开关窗口宽度随其时间非对称量作周期性变化，周期为控制脉冲周期的一半。理论计算结果与实验结果完全吻合。The effects of NLE offset on the switching window of a terahertz optical asymmetric demultiplexer (TOAD) are investigated by using unmerical simulation.The results show that the switching window width of TOAD changes periodically with the time asymmetry of TOAD and the period is one half of the period of control pulses.The theoretical results agree with the experimental results very well.In this paper,we discover a new widow which can be used to demultiplex the data signal.
