I want to add that 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. Depending on your application you can choose between three transmitters: NRZ or NRZ, RZ and CS-RZ or a transmitter that supports six modulation formats: NRZ, RZ and CS-RZ and the three corresponding DPSK versions. As receivers we offer a photo receiver for NRZ, RZ and CS-RZ as well as a receiver for DPSK with built in decoder and a balanced detector. You may refer to this link.
