Abstract：
Physiological networks, as observed in the human organism, involve multi-component systems with feedback loops that contribute to self-regulation. Physiological phenomena accompanied by time-delay effects may lead to oscillatory and even chaotic dynamics in their behaviors. Analogous dynamics are found in semiconductor lasers subjected to delayed optical feedback, where the dynamics typically include a time-delay signature. In many applications of semiconductor lasers, the suppression of the time-delay signature is essential, and hence several approaches have been adopted for that purpose. In this paper, experimental results are presented wherein photonic filters utilized in order to suppress time-delay signatures in semiconductor lasers subjected to delayed optical feedback effects. Two types of semiconductor lasers are used: discrete-mode semiconductor lasers and vertical-cavity surface-emitting lasers (VCSELs). It is shown that with the use of photonic filters, a complete suppression of the time-delay signature may be affected in discrete-mode semiconductor lasers, but a remnant of the signature persists in VCSELs. These results contribute to the broader understanding of time-delay effects in complex systems. The exploration of photonic filters as a means to suppress time-delay signatures opens avenues for potential applications in diverse fields, extending the interdisciplinary nature of this study.
摘要：
生理网络，正如在人类有机体中观察到的那样，涉及具有有助于自我调节的反馈回路的多组分系统。伴随时间延迟效应的生理现象可能导致其行为的振荡甚至混沌动力学。在受到延迟光学反馈的半导体激光器中发现了类似的动力学，其中动态通常包括时间延迟签名。在半导体激光器的许多应用中，抑制时间延迟签名是必不可少的，因此，为此目的采用了几种方法。在本文中,给出了实验结果，其中利用光子滤波器来抑制受到延迟光学反馈效应的半导体激光器中的时间延迟特征。使用两种类型的半导体激光器:离散模式半导体激光器和垂直腔面发射激光器(VCSEL)。结果表明，随着光子滤波器的使用，在离散模式半导体激光器中，时间延迟特征的完全抑制可能会受到影响，但是在VCSEL中仍然存在签名的剩余部分。这些结果有助于更广泛地理解复杂系统中的时间延迟效应。光子滤波器作为抑制时间延迟特征的手段的探索为不同领域的潜在应用开辟了途径。扩展了这项研究的跨学科性质。
