By injecting chaos into chaos, more complex chaotic waveforms can be generated to enhance the chaotic complexity and the communication system confidentiality. Chaotic secure communication has a great application prospect in the secure communication field and has attracted extensive attention from researchers at home and abroad.Д«ased on two parallel electro-optic delay feedback loops, an electro-optic intensity chaotic system is designed in this paper. With the chaotic signal has the advantages of aperiodic, continuous broadband spectrum, noise-like, and unpredictable long-term, information is hidden in chaotic signals for transmission, and the transmitted information is demodulated by the chaotic waveform synchronized with the transmitter at the receiver. Chaotic secure communication is the physical hardware encryption based on chaotic signals. Therefore, it is very necessary to encrypt the signal transmitted in optical fibers. However, during the transmission process, there is a risk of being eavesdropped on by illegal receivers. Overview: With the increase in demand for communication capacity, speed, and confidentiality, optical fiber communication has become an important way of information transmission.

Chaotic laser parallel series synchronization and its repeater applications in secure communication. Numerical simulations show that the proposed method is feasible to simulate the optical feedback loop, and the simulation results are in good agreement with the theoretical values, which prove that the chaotic signal is generated.

The article introduces how to use MATLAB and OptiSystem software to realize the co-simulation of chaotic systems. The electro-optic delay feedback loops are realized by the MATLAB program, and the signal transmission in optical fibers is completed in the OptiSystem software. The mature laser and binary sequence generation modules in OptiSystem software provide energy and input signals for the system. In this design, MATLAB and OptiSystem software are used to simulate the system, which solves the problem that OptiSystem software can't simulate the optical feedback loop. By injecting chaos into chaos, a more complex chaotic waveform is generated to enhance the chaotic complexity and the communication system confidentiality. An electro-optic intensity chaotic communication system is designed by combining two electro-optic delay feedback loops with parallel structures.
