Abstract :
A travelling-wave electrode electroabsorption modulator integrated distributed feedback laser to overcome the CR-induced bandwidth limitation is developed. A bandwidth much wider than 50 GHz is achieved. A 40 Gbit/s eye-diagram is observed. The device has a potentiality for future 100 Gbit/s transmission
