TL;DR: The time delay (TD) signature suppression of chaotic output in a double optical feedback semiconductor laser (DOF-SL) system is experimentally and numerically demonstrated.

TL;DR: This proposal lowers the requirement for wideband chaos generation and synchronization in high-speed long-distance chaotic optical communications, and fiber dispersion compensation can also be simplified, which has potential to be used in high speed long- distance secure optical communications.

TL;DR: A novel dual-channel chaotic synchronization configuration, constructed on the basis of two unidirectionally coupled vertical-cavity surface-emitting lasers, which has higher tolerance to mismatched parameters and under the additive chaos modulation (ACM) encryption scheme, the encoded messages can be successfully extracted for both of orthogonal LP modes.

TL;DR: Using two mutually coupled semiconductor lasers (MC-SLs) outputs as chaotic entropy sources, a scheme for generating Tbits/s ultra-fast physical random bit (PRB) is demonstrated and analyzed experimentally.

TL;DR: A reservoir computing system based on a semiconductor laser with double optical feedback and optical injection with good prediction performance is proposed, and the prediction performance of such a system is numerically investigated via Santa Fe Time-Series Prediction task.
