Abstract

We propose an approach to enhance chaos bandwidth using a cascade intensity-modulated optical injection system. The study focuses on the interaction between the multi-wavelength laser, caused by intensity modulation, and the injected laser to explain the mechanisms underlying the enhancement of chaos bandwidth. Specifically, the influences of injection parameters and intensity-modulated laser characteristics on chaos bandwidth are analyzed in detail. Experimental results show that cascade intensity-modulated optical injection significantly enhances chaos bandwidth through the mode beating effect between modulation side modes and the injected laser oscillation mode. The findings not only clarify the physical mechanism behind chaos bandwidth enhancement but also provide valuable guidance for further enhancing the chaos bandwidth.

利用级联强度调制光注入增强混沌带宽

我们提出了一种利用级联强度调制光注入系统来增强混沌带宽的方法。重点研究了由强度调制引起的多波长激光与注入激光之间的相互作用，以解释混沌带宽增强的机制。详细分析了注入参数和光强调制特性对混沌带宽的影响。实验结果表明，级联强调制光注入通过调制侧模式与注入激光振荡模式之间的模式跳动效应显著提高了混沌带宽。研究结果不仅阐明了混沌带宽增强的物理机制，也为进一步增强混沌带宽提供了有价值的指导。
