Journal ArticleDOI
Highly Correlated Chaotic Emission From Bidirectionally Coupled Semiconductor Lasers
TL;DR: This work investigates a bidirectional coupling topology, with two or more SLs coupled with a common hub SL, which leads to an unprecedented level of synchronization, which promotes the proposed topology for cryptographic applications.
Proceedings ArticleDOI
Enhancement of the Encryption Efficiency of Chaotic Communications Based on All-optical Feedback Chaos Generation by Means of Subcarrier Modulation
TL;DR: The encryption efficiency of the chaotic carrier, which is defined as the signal-to-noise ratio (SNR) of the encrypted message after filtering the combined signal of chaos and signal, is considered as the basic measure of the offered security.
Journal ArticleDOI
Time-Scale Independent Permutation Entropy of a Photonic Integrated Device
TL;DR: In this paper, a new measure of complexity, time-scale independent permutation entropy, has been developed and applied to fully characterize the relative complexity of the emission of a four-section photonic integration chip (PIC) laser.
Journal ArticleDOI
Hurst exponents and cyclic scenarios in a photonic integrated circuit.
TL;DR: There is an indication of the most effective operating regions with minimized predictability, which hinders eavesdropping and the progress of forecasting the development of the chaotic light carrier.
Journal ArticleDOI
Effects of Ge concentration, boron co‐doping, and hydrogenation on fiber Bragg grating characteristics
TL;DR: In this article, the authors compare photosensitivity, refractive-index modulation depth, spectral bandwidth, and excess loss through the inscription of fiber Bragg gratings in unloaded and hydrogen-loaded fibers with low or high Germanium concentration and boron co-doping.
