Abstract: The Chaos in single-mode semiconductor lasers is generated by means of an optoelectronic feedback. Chaotic dynamics have been generated due to the semiconductor laser model with optoelectronics feedback under appropriate conditions. MATLAB packages have been used to simulate the behavior of the semiconductor laser diodes with optoelectronics feedback. According to the chaos simulation technique, we have studied the model properties. And determine the control parameters that lead to regular behavior. Chaotic behavior has been generated by use the simulated model of OEFSL under appropriate conditions. We have a lot consider effectively analyze the behavior of a dynamical system under the influence control parameters such as bias current (delta(0)), feedback strength (epsilon) and the population inversion (gamma).
