Abstract

In this paper, from the SIMULINK visual modeling requirements, the rate equations of the master-slave semiconductor lasers are derived and improved, the corresponding models are constructed, and the rate equations are calculated using the fourth-order Runge-Kutta algorithm. Finally, this visualization model is used to study the effects of delay parameter and injection intensity on the chaotic synchronous communication performance of the optical injection feedback semiconductor laser. The results show that the increasing injection intensity leads to an increasing number of master-slave semiconductor laser interrelationships, while the magnitude of the delay parameter has little effect on the degree of interrelationship of the chaotic synchronous system.
