Chaotic lasers are widely used in secure communication, optical detection and other applications due to their noise-like randomness, excellent anti-jamming and other advantages. This research looks into the chaotic laser's performance at a low cost. The performance related to a semiconductor laser with double delayed feedback is observed and its characteristics are determined in experimental research utilizing OptiSystem simulator. The chaotic laser output is fed back to the Mach-Zehnder modulator (MZM) to make the original system. The gain coefficient changes dynamically, and a second time delay is introduced into the system. The feedback time and feedback strength of the improved chaotic system are studied under varying input bias current, frequency and modulation beak current. Bifurcation diagram results show that the chaotic laser output by the optoelectronic oscillator (OEO) is more complex and has lower delay characteristics. This method does not increase too much Under the premise of system cost, more complex chaotic signals can be generated, and the signal delay characteristics can be reduced, which is conducive to improving the security of the communication system.

“…As the core device of modern electronic systems such as communication, radar and electronic measurement, microwave local oscillator sources have always been an important research content in the field of microwave photonics. In order to meet the needs of broadband, real-time and precise applications, microwave photonic technologies including photogenerated microwaves still need to be further studied to further improve performance indicators [4]. According to the needs of 5G communication systems, increasing the tunable bandwidth, reducing phase noise, and enhancing the ability to resist electromagnetic interference have become new directions for oscillator research.…”

The oscillator is the core module of the radio frequency receiving front-end, which directly determines the signal processing capability of the communication system. Optoel Electronic Oscillator (OEO) technology has become the main research direction to solve the indicators of improving phase noise and frequency tuning range of RF receiving front-end. In order to better solve the problem of RF reception, this paper studies the coupled optoelectronic oscillator, discusses its application in 5G communication systems, and discusses the voltage-controlled tunable fiber Fiber Fabry-Perot Coupled Optoel Ectronic Oscillator (FFP-COEO); Phase noise phase and frequency tuning model, the oscillator controls the cavity length of the Fabry-Perot cavity by voltage, and the starting frequency can be adjusted. The experimental results show that the oscillator can increase the secondary mode-locked loop by improving the filtering performance of the optical loop, further optimize the phase noise of the system, and improve the side mode suppression ratio and output power.
