提出了一种利用自脉动半导体激光器实现光混沌通信的同步方案。通过在自脉动激光二极管中注入正弦电子信号，可以获得光学混沌光。为了实现两个具有不同初始条件的完全相同的混沌系统之间的同步，根据Pecora和Carroll的理论，建立了驱动响应系统模型。如果驱动和响应系统的条件Lyapunov指数都为负，则可以实现光单工和双工传输的同步。该方法为实现光学混沌调制解调提供了关键一步。
A synchronization scheme using self-pulsating laser diodes in optical chaotic communication is proposed. Optical chaotic light can be obtained by injecting a sinusoidal electronic signal into a self-pulsating laser diode. To synchronize between two identical chaotic systems with different initial conditions, a drive and response system model is constructed according to Pecora and Carroll's theory. Synchronization can be achieved for optical simplex and duplex transmissions provided that the conditional Lyapunov exponents for the drive and response systems are all negative. This approach offers a key step toward realizing optical chaotic modulation and demodulation.
