研究目的
Investigating the generation of a tunable self-mixing chaotic laser based on high frequency electro-optical modulation for applications in high-speed broadband communication and sensing.
研究成果
The proposed system successfully generates an ultra-wide band chaotic laser from 0.8 GHz to 24 GHz, demonstrating its suitability for high-speed broadband communication and sensing. The tunable chaotic laser signal production method is effective, with a highly sensitive dynamic response near the 2.0 GHz range.
研究不足
The study focuses on the effect of frequency modulation on the bandwidth of chaotic laser and does not explore other modulation parameters or environmental factors that might affect the system's performance.
1：Experimental Design and Method Selection:
A laser dynamics system is designed as a double ring resonator for tunable chaotic laser generation, incorporating optical feedback and electro-optic modulation.
2：Sample Selection and Data Sources:
The system uses a pump laser at 980 nm, erbium-doped fiber (EDF), and other optical components to generate and modulate the laser.
3：List of Experimental Equipment and Materials:
Includes a pump laser, WDM, EDF, FBG, optical couplers (OC-1, OC-2), EOM, VOA, EDFA, PD, and ESA.
4：Experimental Procedures and Operational Workflow:
The system is tested by modulating the frequency from 10 MHz to 10 GHz, and the output is analyzed using ESA and OSA.
5：Data Analysis Methods:
The chaotic state and bandwidth are analyzed through spectral responses and chaotic series.
