In this paper, we demonstrate how a semiconductor laser under single and dual optical injection can act as a high-speed, reconfigurable nonlinear element. By achieving an excellent agreement between the theoretical model and experimental measurements, the study confirms the predictive strength and robustness of our model, which accurately captures the underlying physics of optical nonlinearities.<\/p>\n\n\n\n

\u26a1 Rapid nonlinear responses at high data rates
\ud83d\udd27 Programmability using optical control signals
\ud83d\udcc9 The ability to implement various activation profiles (e.g., sigmoid-like, saturating behaviors) entirely in the optical domain
\ud83d\udd0b Very low energy consumption per nonlinear operation, making it suitable for integration into next-generation photonic systems<\/p>\n\n\n\n
The work also presents an early-stage validation, demonstrating the feasibility of using Fabry\u2013P\u00e9rot laser diodes as building blocks for scalable, all-optical neural network architectures that operate at ultrafast speeds with minimal energy cost.
