在光电电路中实现延时反馈可以让人们发现非线性动力学丰富的物理特性和应用潜力。例如，重要的反馈效应是宽带混沌的产生或激光自脉冲。我们探索了在腔量子电动力学（cQED）范围内运行的超紧凑微型激光-微型探测器组件中光电反馈的影响。该系统用于在微型激光器的发射中产生 MHz 频率的自脉冲，并通过考虑 cQED 效应的速率方程模型对其进行定性解释。结果表明，探索超紧凑纳米光子系统中的混沌以及在高度集成的半导体平台上实现基于混沌的安全通信、随机数生成和自脉冲单光子源的技术方法具有前景。
Implementing time-delayed feedback in optoelectronic circuits allows one to uncover the rich physics and application potential of nonlinear dynamics. Important feedback effects are, for instance, the generation of broadband chaos, or laser self-pulsing. We explore the effect of optoelectronic feedback in an ultracompact microlaser–microdetector assembly operating in the regime of cavity quantum electrodynamics (cQED). This system is used to generate self-pulsing at MHz frequencies in the emission of a microlaser, which is qualitatively explained by a rate equation model taking cQED effects into account. The results show promise for exploring chaos in ultracompact nanophotonic systems and for technological approaches toward chaos-based secure communication, random number generation, and self-pulsed single photon sources on a highly integrated semiconductor platform.
