On the Universality of Microwave Envelope Equations for Narrowband Optoelectronic Oscillators

Journal of Lightwave Technology, 2022
Narrowband optoelectronic oscillators are time-delayed system that can generate ultrapure microwave signals. In order to study these oscillators, one approach is to derive a time-delayed envelope equation.

Optoelectronic oscillators with time-delayed feedback

Reviews of Modern Physics, 2019
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 both theoretically and experimentally, leading to a better understanding ...

A normal form method for the determination of oscillations characteristics near the primary Hopf bifurcation in bandpass optoelectronic oscillators: Theory and experiment.

Chaos, 2019
We propose a framework for the analysis of the integro-differential delay Ikeda equations ruling the dynamics of bandpass optoelectronic oscillators (OEOs). Our framework is based on the normal form reduction of OEOs and helps in the determination of the

Dynamics of Wideband Time-Delayed Optoelectronic Oscillators With Nonlinear Filters

IEEE Journal of Quantum Electronics, 2019
We present a theoretical and experimental study of an optoelectronic oscillator featuring a cubic-nonlinear filter in the feedback loop. In this architecture, the nonlinearity introduces an additional timescale that leads to the emergence of complex ...

Novel architectures of optoelectronic oscillators

Terahertz, RF, Millimeter, and Submillimeter-Wave Technology and Applications XI, 2018
We present a theoretical and experimental study of novel architectures of optoelectronic oscillators that have a nonlinear response in the electric branch. We perform a nonlinear analysis and obtain a good comparison between our theoretical results and the experimental measurements.

Classification of IQ-Modulated Signals Based on Reservoir Computing With Narrowband Optoelectronic Oscillators

IEEE Journal of Quantum Electronics, 2021
We numerically perform the classification of IQ-modulated radiofrequency signals using reservoir computing based on narrowband optoelectronic oscillators (OEOs) driven by a continuous-wave semiconductor laser.

Frequency Shifts Estimation for Sensors Based on Optoelectronic Oscillators

IEEE Sensors Journal, 2021
Optoelectronic oscillators (OEO) based sensors generate low-phase-noise signals, whose frequency is in the order of GHz. These sensors are highly sensitive to parameters like strain, transverse load or temperature.
