Time-delayed optoelectronic oscillators are at the center of a large body of scientific
literature. The complex behavior of these nonlinear oscillators has been thoroughly explored …

Nonlinear time series analysis is an active field of research that studies the structure of
complex signals in order to derive information of the process that generated those series, for …

In this paper an approach to identify delay phenomena from time series is developed. We
show that it is possible to perform a reliable time delay identification by using quantifiers …

We report on successful 10 Gb/s transmission of a message hidden in a chaotic optical
phase over more than 100 km of an installed fiber optic network. This represents the best …

In this paper, a novel electro-optic feedback phase chaotic system based on nonlinear
coupling of two delayed interfering branches is proposed and analyzed by numerical …

Using the machine learning approach known as reservoir computing, it is possible to train
one dynamical system to emulate another. We show that such trained reservoir computers …

Chaotic dynamics of a semiconductor laser subject to optical feedback from a frequency-
detuned fiber Bragg grating (FBG) is investigated experimentally and numerically. Although …

We introduce a scheme that integrates a digital key in a phase-chaos electro-optical delay
system for optical chaos communications. A pseudorandom binary sequence (PRBS) is …

Security in information exchange plays a central role in the deployment of modern
communication systems. Besides algorithms, chaos is exploited as a real-time high-speed …

We propose and experimentally study a coherent optical secure transmission system based
on one dual-polarization in-phase and quadrature modulator (IQM). One beam of the …
