Time delay signature of chaotic nanolasers and its concealment

In this paper, we investigate the presence of time delay (TD) signature in chaotic intensity outputs of nanolasers subject to different optical feedbacks (OFs). Simulation results reveal the occurrence of obvious TD feature for the cases where conventional, phase conjugate and grating mirror feedbac...

Summary:In this paper, we investigate the presence of time delay (TD) signature in chaotic intensity outputs of nanolasers subject to different optical feedbacks (OFs). Simulation results reveal the occurrence of obvious TD feature for the cases where conventional, phase conjugate and grating mirror feedbacks are employed. So, a proposed scheme for generating optical chaos with concealed TD signature is proposed to overcome the drawbacks of previously mentioned OFs and render the system more appropriate for applications of secure communications and fast physical random number generators.
