title = "Suppressed time delay signature in chaotic nanolasers with hybrid feedback",
abstract = "In this paper, we investigate the presence of time delay (TD) signature in the chaotic emission of semiconductor metalclad nanolasers subject to different types of optical feedbacks (OFs). We first examine the TD signatures in the cases when all-optical feedback via either conventional mirror, phase conjugate mirror, or grating mirror is employed. Second, we propose a mixed all-optical/electrooptic feedback scheme for concurrent suppression of TD feature in chaotic output emission. The mathematical model for proposed scheme is presented to integrate both the optical and electrooptic time delays. The concealment of TD signature is then investigated by means of the autocorrelation function. The results reveal that the chaotic output signal in each case has well eliminated TD signature at particular operational regions within which the system is more appropriate for applications related to secure communications and ultra-fast physical random number generators.",
