Abstract :
We experimentally characterize and compensate the amplitude and phase distortion of externally modulated radio over fiber link (RoF) using mixed polarization electro-optical modulator (EOM). The mixed polarization makes use of the polarization dependent electro-optic coefficients of the EOM to suppress nonlinear distortion. The AM-AM compression and AM-PM conversion are newly expressed and directly evaluated from static one tone measured S21. The P1dB compression is improved by more than 4 dB experimentally.
