提出了一种新型的基于半导体光纤环形腔激光器(SFRL)中同时发生的四波混频效应和交叉增益调制效应同时实现全光AND门和NOR门方案,并建立了这种全光逻辑门完整的宽带理论模型.通过数值模拟的方法,研究了输入信号光峰值功率及SFRL中两个耦合器的耦合比对这种全光逻辑门输出特性的影响.
A new type of all-optical AND gate and NOR gate based on the simultaneous four-wave mixing effect and cross-gain modulation effect in semiconductor fiber ring resonator (SFRL) is proposed. The complete optical logic gate complete Of the broadband theoretical model.A numerical simulation of the peak power of the input signal and the coupling ratio of two couplers in the SFRL have been used to investigate the output characteristics of this all-optical logic gate.
