英文摘要	在半导体光放大器中当光脉冲小于10 ps时除了考虑线性增益饱和效应,还必须考虑超快增益压缩效应.本文用数值方法分析了超快增益压缩效应对THz光非对称解复用器(TOAD)的开关特性.经过细致的参数优化,采用2.5 ps控制光,可以克服开关窗的分裂效应,得到一个宽度为2.0 ps,消光比为13. 7 dB的开关窗.; Ultrafast ga in compression has to be considered besides the linear gain saturation when opti cal pulses shorter than 10 ps are involved in semiconductor optical amplifiers ( SOA).In this paper,the influence of the ultrafast gain compression on the switch ing performance of a THz optical asymmetric demultiplexer (TOAD) due to ca rrier heating and other nonlinear processes in the SOA is numerically analyzed.I t is shown that the breakup effect of the switching window can be circumvented a nd a window width of 2.0 ps with an extinction ratio of 13.7 dB can be achieved at a control pulsewidth of 2.5 ps through careful parameter optimization.; foundation from Ministry of Education and National Key Lab in Integ Opeoelectronics in China; 0; 5; 484-489; 11
