Self-induced chaos in a laser diode Twyman–Green interferometer with an optoelectronic delayed feedback is studied. We have experimentally observed the chaotic behavior of the laser output power, which involves period-doubling bifurcation schemes. A linearized stability analysis is performed, which predicts the stability condition. The numerical simulations of the difference equation of the system qualitatively reproduce the results of the experiment. We also discuss the evolution’s route to chaos based on the change of the trajectories in the phase space.
