We demonstrate that the dynamics of an autonomous chaotic laser can be controlled to a periodic or steady state under self-synchronization. In general, past the chaos threshold the dependence of the laser output on feedback applied to the pump is submerged in the Lorenz-like chaotic pulsation. However there exist specific feedback delays that stabilize the chaos to periodic behavior or even steady state. The range of control depends critically on the feedback delay time and amplitude. Our experimental results are compared with the complex Lorenz equations which show good agreement.
我们证明,在自同步条件下,自主混沌激光器的动力学可以被控制到周期态或稳态。一般来说,超过混沌阈值后,激光器输出对施加在泵浦上的反馈的依赖性就会淹没在类洛伦兹混沌脉动中。然而,存在特定的反馈延迟,可将混沌稳定为周期性行为甚至稳态。控制范围关键取决于反馈延迟时间和幅度。我们将实验结果与复杂的洛伦兹方程进行了比较,结果显示出良好的一致性。
