摘　　要：提出一种基于级联单端半导体光放大器 (SOA)中交叉增益调制效应的新型全光逻辑与门 ,建立了该方案的理论模型 ,数值模拟和实验实现了 10Gb s的全光逻辑与运算功能 ,分析了逻辑与运算结果与输入信号功率和消光比之间的关系 ,理论分析结果与实验结果相符合 .A novel scheme based on cross-gain modulation in cascaded single-port-coupled semiconductor optical amplifier(SOA) is studied theoretically and experimentally. Theoretical model for the single-port-coupled SOA is established for theoretical simulation and performance evaluation. The 10Gb/s all-optical logic AND operation has been demonstrated theoretically and experimentally. A parameter is exploited to evaluate the output performance. Results show that the output performance is tightly related to input power and input extinction ratio. Theoretical calculation results are in agreement with the experimental results.
