RF photonics technology such as Radio-over-fiber (RoF) is a way to distribute RF signals to base stations and Cable TV networks [3–5]. In RoF direct modulation transmission systems, the input current of a semiconductor laser is directly modulated by the information-bearing RF signal. Due to the nonlinear relationship between the input current and the output optical power of the semiconductor laser, distortion is introduced to the RoF transmission system.
