  • 在一个双光反馈半导体激光混沌系统中,固定其中一个反馈腔镜(固定腔M1)的反馈延迟时间以及反馈强度,实验研究了另一个反馈腔镜(可变腔M2)的反馈延迟时间以及反馈强度对系统混沌输出的延时反馈特征的影响.研究结果表明:在可变腔M2与固定腔M1的反馈强度相等的条件下,改变M2的腔长,当其腔长约等于(但不能严格等于)M1的腔长或者腔长的一半时,系统将呈现较好地抑制延时反馈特征效果;当M
    In a double optical feedback semiconductor laser chaotic system, by fixing the feedback time and feedback strength of the one mirror (named as fixed cavity M1), the influences of the feedback time and feedback strength of the other mirror (named as tunable cavity M2) on the time delay feedback signatures of the chaotic system have been investigated experimentally. The results show that, for the case of the two cavities with identical feedback strengths, time delay feedback signatures of chaotic output can be suppressed efficiently when the cavity length of M2 is approximately equal (but can not exactly equal) to the cavity length of M1 (or half of the cavity length of M1). Fixing the length of M2 to approximately equal to the cavity length of M1 (or half of the cavity length of M1), the time delay feedback signature suppression can be further improved through adjusting the feedback strength of M2 carefully. Therefore, adopting a double optical feedback semiconductor laser chaotic system can make the system behave with higher security due to the efficient hiding of delay feedback parameter of the system.
