In this paper we address the limiting effect of power fading (PF) in fiber optic communication links, due to the fiber’s dispersive properties, and suggest a mitigation approach in intensity-modulated radio-over-fiber (RoF) applications. The proposed method is independent of the length of the optical transmission path. PF is mitigated by employing a simple integrated photonic structure, i.e., a single micro-ring resonator. The latter features a periodic notch-filter response, employed to suppress one of the sidebands in an optical double sideband (ODSB) modulation, reducing the PF of the received RF signal. The suppression ratio measured by the optical spectrum analyzer is 24 dB. In this way we succeeded in reducing the RF signal’s power ripple at the receiving end to 3 dB. The proposed approach promises an economic yet effective solution to overcoming the PF in point-to-multipoint-topology optical networks.
