对偏置电流不对称的互耦合半导体激光器的混沌同步特性进行了实验和数值研究。实验结果表明，两个MCSL之间的不对称偏置电流水平对它们之间的混沌同步有明显的影响，在较大的不对称偏置电流水平下可以实现稳定的超前滞后混沌同步。此外，还讨论了两个激光器之间的频率失谐和相互耦合强度对混沌同步性能的影响。理论模拟与我们的实验观测基本一致。(C)2011年美国光学学会
We experimentally and numerically investigated the chaos synchronization characteristics of mutually coupled semiconductor lasers (MCSLs) with asymmetrical bias currents. Experimental results show that, asymmetrical bias current level of two MCSLs has obvious influence on chaos synchronization between them, and stable leader-laggard chaos synchronization can be realized under relatively large asymmetrical bias current levels. Moreover, the influences of frequency detuning and mutually coupling strength between the two lasers on chaos synchronization performance have also been discussed. Theoretical simulations basically conform to our experimental observations. (C)2011 Optical Society of America
