摘　　要：基于太赫兹光非对称解复用器(TOAD),提出了一种全光或门的实现方案 从TOAD原理出发,从理论上证实了该方案实现全光或运算的可行性 在此基础上进行了实验研究,成功实现了10Gb/s的全光或运算 实验采用1100和0110编码的两路数据信号,完全验证了或运算真值表中各种可能的情况,并显示出该方案对实现任意编码或伪随机码数据或运算的潜力 对SOA增益恢复时间对结果的影响提出了改进办法 最后分析表明。A scheme for all-optical OR gate is proposed based on teraherz optical asymmetric demultiplexer (TOAD). The feasibility of this scheme is theoretically analyzed with the principle of TOAD. Based on this, all-optical OR gate operation at 10 Gb/s is successfully demonstrated. Two data signals coded 1100 and 0110 are used in the experiment, giving chance to demonstrate all of the possibilities of OR gate operation. The successful demonstration of such kinds of codes also shows the potential of this scheme to process OR gate operation on data with arbitrary codes or data of pseudo-random bit streams (PRBS). For the influence of the gain recovery time of SOA, optimising method is proposed. Analysis shows that with this scheme, ultrafast and high extinction ratio OR gate operation can be performed.
