摘　　要：建立了基于SOA-MZI结构差分相位法的全光异或逻辑门模型,实现了20 Gbit/s信号的全光异或逻辑运算。运算结果表明:输出脉冲信号的宽度主要是由延迟时间t决定的。采用差分相位法,可以减弱输出脉冲的码型效应,避免出现"拖尾"现象。A scheme for all-optical XOR logic gate using differential phase method has been investigated. The experimental results for XOR gate at 20Gbit/s are presented. The results show that the width of output pulse is mainly determined by delay time. The pattern effect of the output pulse can be weakened, and the ＂tail＂ phenomenon can be avoided by using differential phase scheme.
