论文摘要
耦合半导体激光器的阵列是具有根本复杂的动力学的系统，使其可用于在光束形成和光束形状中的众多应用中有用。在这项工作中，我们研究了在耦合光子二聚体阵列中振荡振幅的空间可控性，每个二聚体均由两个由差分抽水速率驱动的半导体激光器组成。我们考虑了每个二聚体稳定的相锁状态的参数值，通过HOPF分叉变得不稳定，我们表明，通过将适当的泵浦速率值分配给每个二聚体，大振幅振荡，并存，幅度较小的幅度振荡振荡。空间轮廓？跨数组的振荡幅度可以通过每个二聚体中适当的抽水速率值动态控制。即使对于激光器之间的随机失谐，该特征也很健壮，并提出了一种动态重新配置的激光振幅振荡空间轮廓多样性的机制。
Arrays of coupled semiconductor lasers are systems possessing radically complex dynamics that makes them useful for numerous applications in beam forming and beam shaping. In this work, we investigate the spatial controllability of oscillation amplitudes in an array of coupled photonic dimers, each consisting of two semiconductor lasers driven by differential pumping rates. We consider parameter values for which each dimer's stable phase-locked state has become unstable through a Hopf bifurcation and we show that, by assigning appropriate pumping rate values to each dimer, large-amplitude oscillations coexist with negligibly small amplitude oscillations. The spatial profile? of the amplitude of oscillations across the array can be dynamically controlled by appropriate pumping rate values in each dimer. This feature is shown to be quite robust, even for random detuning between the lasers, and suggests a mechanism for dynamically reconfigurable production of a large diversity of spatial profiles of laser amplitude oscillations.
