Nonlinear Distortion Suppression Scheme in Optical Direct FM Radio-on-Fiber System

This paper proposes a nonlinear distortion suppression scheme for optical direct FM Radio-on-Fiber system. This scheme uses the interaction between the nonlinearities of DFM-LD and OFD to suppress a 3rd order intermodulation distortion. We theoretically analyze the carrier to noise-plusdistortion ratio (CNDR) and show a controlling method in the MZI type OFD to realize the proposed suppression scheme. key words: radio-onber, SCM, DFM-LD, OFD, 3rd order
