Abstract

In this study, we investigate the dynamics of quantum dot lasers under optical feedback. In this system of rate equations, the output laser exhibits nonlinear behavior such as chaotic dynamics at different values ​​of the parameters. Change parameters such injection current and optical  feedback strength. Finding the frequencies  with  fast  Fourier transform (FFT) for different values of parameters.  The rate equation is solved numerically using the delay differential method (dde23) in the MAT LAB program.
