Unveiling Chaos in Semiconductor Lasers: A Simulation-Based Study Using Vicente Equations
Author:
Abstract: This paper presents a simulation study for a semiconductor laser with optical feedback based on the Lang-Kobayashi model. The analysis of the system’s dynamical behavior, utilized using Vicente equations, has provided evidence of the presence of chaotic behavior. Performing detailed numerical simulations, we have explored the parameters, revealing the transitions of the system from stable operation to chaotic. Our findings corroborate previous theoretical predictions and offer new insights into the complex behavior of semiconductor lasers under feedback conditions. The results have significant implications for applications where controlled chaotic behavior is desirable, such as secure communications and random number generation.
