Paper Abstract

This paper introduces a new bidirectional mmRoF system based on optical frequency multiplication (OFM) scheme using dual drive Mach-Zehnder Modulator (DD-MZM) and OFDM modulation. The emphasis is put on the optimization of optical modulation index to the MZ intensity modulator for OFDM signal with high PAR which imposes a limitation on the system bit error rate (BER) performance due to the nonlinearity of the MZ modulator. The theoretic analysis on carrier to composite triple beat ratio is performed. The extension to system BER for QAM format is presented and the experimental proof is given in a 40 GHz mmRoF system.
