| 摘 要： | 文中提出了一种基于改进的太赫非对称光解复用器（TOAD：Terahertz Optical Asymmetric Demultiplexer）结构和差分调制的方案，用以完成光分组交换网络中的全光分组级信头提取。分组包中信头与净荷的速率分别为2．5Gbit／s和40Gbit／s。经数值仿真得到系统对信头和净荷的开关比可达15dB以上。此外，还具体讨论了SOA-TOAD的系统参数对性能的影响，从而得到使其性能优化的系统参数。

| Abstract: | A novel serial scheme of header extraction for optical packet switched networks based on a modified Terahertz Optical Asymmetric Demultiplexer(TOAD) with differential modulation scheme is proposed.Numerical analysis and simulation show that more than 15dB contrast ratio of the separated header at 2.5Gbit/s to the suppressed payload at 40Gbit/s can be achieved.In addition,the SOA-TOAD parameters are discussed and designed to optimize the performance of the proposed scheme. |
