介绍了一种消除半导体激光器耦合阵列在高阈值驱动下混沌涨落的控制方案。利用模型方程，我们证明了阵列的输出场可以稳定到一个稳定的同相状态，其特征在于一个窄的远场光束，只有很小的局部扰动的环境驱动电流参与控制过程。我们进行了线性稳定性分析所需的同步状态，并发现控制的活跃的不稳定模式的数量与阵列中的元素的数量的规模。数值支持我们提出的控制技术在环形阵列和线性阵列的有效性。(C)1996年美国光学学会。
A control scheme for eliminating the chaotic fluctuations observed in coupled arrays of semiconductor lasers driven high above threshold is introduced. Using the model equations, we show that the output field of the array can be stabilized to a steady in-phase state characterized by a narrow far-field optical beam, Only small local perturbations to the ambient drive current are involved in the control procedure. We carry out a linear stability analysis of the desired synchronized state and find that the number of active unstable modes that are controlled scales with the number of elements in the array. Numerical support for the effectiveness of our proposed control technique in both ring arrays and linear arrays is presented. (C) 1996 Optical Society of America.
