摘要: 为了实现基于半导体光放大器的全光逻辑与门,采用了在半导体光放大器构成的马赫-曾德尔干涉仪的基础上,注入外部连续光的方法。以半导体光放大器速率方程为基础,对设计方案进行了理论分析和仿真验证,取得了不同重复周期、不同脉冲宽度的光脉冲序列经过全光逻辑与门操作后的输出数据。结果表明,该方案能对传输速率为10Gbit/s或以下的信号进行正确与运算,同时,外光注入可以有效提高半导体光放大器信号处理速度。这一结果对基于半导体光放大器的全光逻辑的设计是有帮助的。Abstract: With the aid of external optical injection,a novel all-optical logic gate based on Mach-Zehnder interferometer composed of semiconductor optical amplifier(SOA-M-ZI) was proposed.Meanwhile,by means of rate equations of the SOA,the logic AND gat was simulated and analyzed.As a result,the logic AND gate process signals with transmission speed of 10Gbit/s or below,and the external optical injection can effectively enhance the signal processing speed of SOA.It is useful to design all-optical logic gates based on SOA.
