In this work, we propose for the first time a theoretical and experimental study of a novel architecture of optoelectronic oscillators (OEOs) with a nonlinear amplifier. Research on these oscillators is the focus of intense research activities in the microwave photonics community. They are currently amongst the most stable microwave sources at room temperature, and understanding their dynamical properties remains of the highest interest for many areas in applied physics and engineering. In this contribution, we investigate the nonlinear dynamics of our system and perform an exhaustive bifurcation analysis which explains how increasing the oscillator gain leads to chaotic oscillatory states. We found that our novel OEO is of higher-order chaotic compared to the standard one, and is an appropriate entropy source for random numbers generation with low energy consumption. We expect this new oscillator to be a core device in many next-generation microwave photonic systems.

具有非线性放大器的时滞光电振荡器的动力学及其在随机数生成中的潜在应用


在这项工作中，我们首次提出了对带有非线性放大器的光电振荡器（OEO）新型架构的理论和实验研究。对这些振荡器的研究是微波光子学界研究活动的重点。它们是目前室温下最稳定的微波源之一，了解它们的动力学特性仍然是应用物理和工程许多领域的最高兴趣。在这篇文章中，我们研究了系统的非线性动力学，并进行了详尽的分岔分析，解释了增加振荡器增益如何导致混沌振荡状态。我们发现，与标准 OEO 相比，我们的新型 OEO 具有更高阶的混沌性，并且是低能耗随机数生成的合适熵源。我们预计这种新型振荡器将成为许多下一代微波光子系统的核心器件。
