提出多量子阱激光器混沌“主-从-响应”式结构同步系统,研究其并联同步在光学逻辑门中的应用.利用一个注入多量子阱激光器混沌系统注入驱动实现了两个响应多量子阱激光系统的混沌并联同步,同时还获得了“主-从”式结构的混沌同步.基于响应子系统的混沌并联同步思想,提出了全光逻辑门的基本理论模型并定义了计算原则与方法.利用光的外部调制方法对两个驱动光进行调制与控制,让两个响应子系统实现同步与非同步,使系统获得了并具有全光逻辑门函数功能与特点,并成功地进行了数字逻辑计算.具体提出了全光XNOR、NOR、NOT等逻辑门及逻辑计算方法,数值模拟结果证明了系统方案的可行性.
The multi-quantum well laser chaos “master-slave-response ” structure synchronization system is studied to study the application of shunt synchronization in optical logic gate.An injection driven by a multi-quantum well laser chaotic system realizes two response multiple quantum Chaos synchronization of the well laser system and the chaos synchronization of the “master-slave” structure are also obtained.Based on the chaotic parallel synchronization of response subsystems, the basic theoretical model of all-optical logic gate is proposed and the principle of calculation And method.Using the external modulation method of light to modulate and control the two driving lights, the two response subsystems are synchronized and unsynchronized, the system obtains and has the functions and characteristics of all-optical logic gate function and has been successfully carried out Digital logic calculation, and put forward the logic gates such as all-optical XNOR, NOR, NOT and so on. The numerical simulation results prove the feasibility of the system scheme.
