A tunable self-mixing chaotic laser based on high frequency electro-optical modulation is proposed. A laser dynamics system is designed and tested for tunable chaotic laser generation and provides optical feedback and electro-optic modulation with two degrees of freedom. The chaotic laser is generated by optical feedback, and it becomes tunable by high frequency electro-optic modulation. The frequency is modulated from 10 MHz to 10 GHz to test this system, and an ultra-wide band chaotic laser from 0.8 GHz to 24 GHz is measured by an electrical spectrum analyzer (ESA). The experimental results show the generation of a tunable chaotic laser via electro-optic modulation. At the same time, this tunable chaotic laser has a highly sensitive dynamic response near the 2.0 GHz range of frequency modulation. The system is proved to be suitable for applications in high-speed broadband communication and sensing.

提出了一种基于高频电光调制的可调谐自混合混沌激光器。设计并测试了用于生成可调谐混沌激光的激光动力学系统，并提供了两个自由度的光反馈和电光调制。混沌激光是由光反馈产生的，并且通过高频电光调制变得可调谐。频率从10 MHz调制到10 GHz以测试该系统，并通过电子频谱分析仪（ESA）测量0.8 GHz至24 GHz的超宽带混沌激光器。实验结果表明，通过电光调制可以产生可调谐的混沌激光器。同时，这种可调混沌激光器在2.0 GHz频率调制范围附近具有高度敏感的动态响应。
