Abstract:

理论研究耦合反馈半导体激光器混沌同步及其在光学数字逻辑门中的应用,构建了三种基本的全光XNOR,NOR,NOT门以及光电复合NOR光学数字逻辑门的物理模型,定义了这些逻辑门的计算原理和方法.基本物理方法是,让外部光注入到2个激光器中产生激光混沌输出,通过两激光器激光的相互耦合及反馈实现混沌同步.在此基础上,利用光的外部调制方法让两相互耦合激光分别在振幅调制下控制混沌同步或非同步,实现了全光逻辑门的功能与计算.然后联合激光的外部调制和激光器电流调制,控制混沌同步或者非同步,实现了光电复合逻辑门的功能与计算.另外,详细地数值分析了激光混沌再同步与再非同步对逻辑输出影响等问题,结果证明了该方案的科学合理性与可行性.
