Systematic or multiple reproduction or distribution to multiple locations via electronic or other means is prohibited and is subject to penalties under law ; A dual-drive LiNbO(3) architecture modulator with chirp management is proposed and developed offering SFDR > 25 dB in a 1.4 V bias excursion compared to only 0.5 V bias excursion in a conventional Mach-Zehnder electro-optical modulator (MZ-EOM). The architecture effectively extends the linear regime and enables the optical transmission of wireless systems employing orthogonal division multiplexing (OFDM) modulation such as ultra-wide band (UWB) which require high linearity over a broad frequency range due to their high peak-to-average power ratio (PARP). Radio-over-fiber UWB transmission in a passive optical network is experimentally demonstrated employing this technique, exhibiting an enhancement of 2.2 dB in EVM after 57 km SSMF when the dual-drive developed modulator is employed. 2011 Optical Society of America ; FP7 FIVER-ICT-4-249142 ; UCELLS-FP7-IST-1-216785 ; Spain FPU MEC grant AP2007-01413 ; EUROFOS NoE ; Morant Pérez, M.; Llorente Sáez, R.; Hauden, J.; Quinlan, T.; Mottet, A.; Walker, S.
