摘　　要：提出了基于两个非对称互注入弱谐振腔法布里-珀罗激光器(weak-resonant-cavity Fabry-Perot laser diodes,WRC-FPLDs)的波长可调谐的混沌同步系统,实验研究了系统的同步性能.结果表明,在一定的非对称注入强度和频率失谐条件下,两个互注入WRC-FPLDs的对应模式之间能实现高质量的超前-滞后混沌同步,最大互相关系数Cmax可达0.90以上.增加两个互注入激光器之间的非对称注入程度并采用适当的负频率失谐有助于提升系统的同步性能.In this paper,a wavelength-tunable chaos synchronization system based on two asymmetric mutually coupled weak-resonant-cavity Fabry-Perot Laser Diodes(WRC-FPLDs)is presented,and the chaos synchronization characteristics are experimentally investigated.The results show that under proper asymmetrical injection strength and frequency detuning,stable leader-laggard chaos synchronization with the maximal correlation coefficient over 0.90 between two corresponding modes in two mutually coupled WRC-FPLDs can be achieved.In addition,the chaos synchronization quality can be improved by enlarging the asymmetrical injection extent between two mutually coupled lasers and adopting a suitable negative detuning frequency.
