Summary:Microwave photonic (MWP) sensing and measurement are envisioned to be a promising alternate to the conventional pure electronic or optical solutions. By using a semiconductor laser (SL) subjected to external optical feedback (EOF) operating at period-one (P1) dynamic state, an MWP signal can be generated for various applications. To assist the design of such MWP sensing system, the paper proposes to use single hidden layer feedforward networks (SLFN) for modeling a laser with optical feedback to generate P-l based MWP signals. The proposed modeling approach can solve the problem of high computational cost in solving the Lang and Kobayashi (L-K) equations to describe SL with EOF system and quickly determine optimal system parameters according to the system performance desired.
