MATLAB Function-Based Single-Loop OEO Simulation Program Using E.C. Levy's Optoelectronic Oscillator Modeling Framework

In his research on optoelectronic oscillator (OEO) modeling, E.C. Levy developed a MATLAB function-based simulation program for single-loop OEO systems. The core objective of this program is to provide numerical simulation support for analyzing OEO dynamic behavior, enabling researchers to thoroughly understand key parameters such as phase noise, spectral characteristics, and stability. The implementation utilizes MATLAB's differential equation solvers and signal processing functions to model the OEO's nonlinear dynamics.

This simulation program can reproduce key results from the research paper, including Figures 2, 4, 5, 8, and 11. These figures potentially encompass OEO time-domain waveforms, spectral distributions, phase noise curves, or closed-loop gain characteristics, depending on parameter configurations in the experimental setup. The program's modular design, implemented through separate function files for different OEO components, allows users to adjust variables such as laser modulation depth, fiber delay line length, or feedback coefficients. This facilitates observation of OEO output response variations under different conditions through parameter sweeping and comparative analysis functions.

The value of this modeling approach lies in its ability to circumvent the costs and uncertainties associated with complex hardware experiments, providing an efficient numerical verification tool for OEO optimization design, such as phase noise reduction or frequency stability improvement. For researchers working in microwave photonics or high-frequency signal generation, this type of simulation program serves as a crucial bridge between theoretical analysis and practical applications, with the MATLAB code offering clear implementation of OEO mathematical models and systematic parameter study capabilities.
