Study of Optical Chaos in a Laser Diode Active Interferometer and its Applications

提出了由具有电子反馈的激光二极管有源干涉仪组成的诺贝尔混沌系统，并对该系统中的混沌进行了研究。在激光二极管的光输出中观察到光的双稳性、多稳性、混沌性以及包括倍周期和间歇性在内的分岔路径。研究了有限时滞对分岔和周期振荡的影响，并观察到一些新的混沌现象。讨论了混沌的应用。通过对可访问控制参数应用混沌控制技术，实验提取了嵌入混沌吸引子中的不同周期轨道。此外，还实现了对周期周期的高模振荡的访问，并证明了其在动态存储器中的潜在应用。

Nobel chaotic system cosisting of a laser diode active interfermoter with electronic feedback is presented and chaos in the delay-differential system is studied. Optical bistability, multistability, chaos, and bifurcation routes including period-doubling and intermittency are observed in the light output of the laser diode. The effects on the bifurcations and the periodic oscillaitons due to the finite delay time are studied and some novel phenomena of chaos are observed. The applications of chaos are also discussed. Different periodic orbits embedded in the chaotic attractors are experimentally extracted by applying a chaos control technique to an accessible control parameter. Furthermore, the access of high mode oscillations of the periodic cycle is realized and its potential application to dynamical memory is demonstrated.
