Abstract :
An optical microwave mixing technique based on optical phase modulation and fiber chromatic dispersion is investigated for up-conversion of IQ modulated microwave subcarriers. Experiments with analog signals have validated up-conversion theory. Error Vector Magnitude measurements have shown low penalty induced by optical microwave up-conversion process on QAM signals within the 10 GHz band. For future radio-over-fiber networks, optical microwave up-conversion in the 60 GHz band is investigated. Application of this technique for high symbol rate IQ modulations for future 60 GHz radio-over-fiber networks is proposed
