Wideband complex-enhanced chaos generation using a semiconductor laser subject to delay-interfered self-phase-modulated feedback.

Review on the broadband time‐delay‐signature‐suppressed chaotic laser

“…46 Jiang et al increased the standard bandwidth of chaotic laser to 30 GHz by using delay-interfered self-phase-modulated feedback in 2019. 47 And they theoretically proved that optical feedback from a parallel coupled ring resonator could also achieve bandwidth enhancement in 2020. 48 Our research group proposed a scheme for the generation of broadband chaotic signal by using a distributed feedback laser diode (DFB-LD) subject to active optical feedback with a HNLF in 2020.…”

“…44 The flatness refers to the range of spectrum fluctuation within the bandwidth. In order to eliminate the influence of relaxation oscillation frequency on the bandwidth and flatness of chaotic laser, researchers have carried out extensive studies, including improved optical feedback, [45][46][47][48][49][50] unidirectional optical injection, [51][52][53][54][55][56][57][58][59] mutual injection, 60,61 and subsequent processing 62,63 of chaotic laser.…”

“…Bouchez et al obtained a wideband chaotic signal with a standard bandwidth of 18 GHz by using phase conjugate feedback in 2019 46 . Jiang et al increased the standard bandwidth of chaotic laser to 30 GHz by using delay‐interfered self‐phase‐modulated feedback in 2019 47 . And they theoretically proved that optical feedback from a parallel coupled ring resonator could also achieve bandwidth enhancement in 2020 48 …”

Exploiting Reservoir Computing for Optical Secure Communication

“…Subsequently, the chaotic secure communication based on chaotic synchronization developed rapidly. Considering the rich dynamic behaviors of semiconductor laser (SL) and its own outstanding characteristics such as high complexity, high bandwidth and low loss [2,3], the SL-based optical chaotic communication has attracted extensive attention and plenty of optical chaotic communication schemes based on the chaotic synchronization have been investigated in the past years [4,5]. The high quality of chaotic synchronization in the traditional optical communication is depend on the well-matched parameters between the transmitter and the receiver.…”

Synchronization of Synchronous Reluctance Motors Using the Discrete Sliding Mode Control Technique

“…A major contribution of chaos theory goes to Lorenz in his work on weather prediction [2]. ese days, chaos can be found in different branches of science including mechanics [3], biology [4], chemistry [5], electronics [6], optics [7], and secure communication [8].…”
