The authors demonstrate an MQW electroabsorption optical modulator with waveguides for 40 Gbit/s modulation. The fabricated device, which is long (1.5 mm) enough for easy fabrication and packaging, shows a record modulation bandwidth of 50 GHz, low driving voltage of 2.8 V and a low insertion loss of 8 dB
