Abstract

We combine gain switching and external optical feedback to achieve high-power coherent pulsing in a large array of semiconductor lasers. The simulations are performed in the framework of the Lang-Kobayashi model with modulation of the electrical bias. Long-range coupling in the network of emitters and precise tuning of the modulation frequency are key parameters to obtain both phase-locking between the emitters, and reproducible, periodic, high intensity bursts, i.e. robust, coherent pulsing. The configuration we present here relies on non-filtered conventional optical feedback and allows achieving phase-locked pulsing across the array, including at modulation frequencies that are resonant and not resonant with the external cavity frequency and its harmonics. This work impacts on the realization of phase-synchronized pulsed sources from semiconductor laser arrays and provides insight for the generation of complex nonlinear dynamics in large networks of oscillators.

优化大型半导体激光器阵列中的相干增益开关脉冲组合
我们结合增益开关和外部光反馈,在大型半导体激光器阵列中实现了高功率相干脉冲。模拟是在郎-小林模型的框架下进行的,并对电偏压进行了调制。发射器网络中的长程耦合和调制频率的精确调整是获得发射器之间锁相以及可重现的周期性高强度脉冲串(即稳健的相干脉冲)的关键参数。我们在此介绍的配置依赖于非滤波传统光反馈,可以在整个阵列中实现锁相脉冲,包括在与外部空腔频率及其谐波共振或不共振的调制频率下。这项工作对实现半导体激光器阵列的相位同步脉冲源产生了影响,并为在大型振荡器网络中产生复杂的非线性动态提供了启示。

期刊介绍: Papers published in the IEEE Journal of Selected Topics in Quantum Electronics fall within the broad field of science and technology of quantum electronics of a device, subsystem, or system-oriented nature. Each issue is devoted to a specific topic within this broad spectrum. Announcements of the topical areas planned for future issues, along with deadlines for receipt of manuscripts, are published in this Journal and in the IEEE Journal of Quantum Electronics. Generally, the scope of manuscripts appropriate to this Journal is the same as that for the IEEE Journal of Quantum Electronics. Manuscripts are published that report original theoretical and/or experimental research results that advance the scientific and technological base of quantum electronics devices, systems, or applications. The Journal is dedicated toward publishing research results that advance the state of the art or add to the understanding of the generation, amplification, modulation, detection, waveguiding, or propagation characteristics of coherent electromagnetic radiation having sub-millimeter and shorter wavelengths. In order to be suitable for publication in this Journal, the content of manuscripts concerned with subject-related research must have a potential impact on advancing the technological base of quantum electronic devices, systems, and/or applications. Potential authors of subject-related research have the responsibility of pointing out this potential impact. System-oriented manuscripts must be concerned with systems that perform a function previously unavailable or that outperform previously established systems that did not use quantum electronic components or concepts. Tutorial and review papers are by invitation only.
