Synchronization due to a weak global coupling with time delay in a semiconductor laser array is investigated both in the cw and self-pulsing regimes. A generalized form of the Kuramoto phase equations is derived and discussed analytically. The time delay is shown to induce in-phase synchronization in all dynamical regimes. Another form of synchronization is found which leads to local extinction of self-pulsing in the array.
研究了半导体激光阵列中由于具有时间延迟的弱全局耦合而导致的同步现象,包括连续波和自脉冲状态。推导了Kuramoto相位方程的广义形式并进行了分析讨论。结果表明,时间延迟在所有动力学状态下都会引起同相同步。还发现了另一种同步形式,它会导致阵列中自脉冲的局部消失。
