An integrated MQW electroabsorption modulator/DFB laser module that operates at 2 V was developed. It offers a 22 dB extinction ratio and 15 GHz bandwidth. 100 km transmission experiments at 20 Gbit/s are carried out using a prototype module. To the best of the authors' knowledge, this is the first report where 20 Gbit/s transmission has been achieved with a monolithically integrated light source.
