Y. Akage et al., Wide bandwidth of over 50GHz travelling-wave electrode electroabsorption modulator integrated DFB lasers, ELECTR LETT, 37(5), 2001, pp. 299-300
A travelling-wave electrode electroabsorption modulatol integrated distribu
ted feedback laser to overcome the CR-induced bandwidth limitation is devel
oped. A bandwidth much wider than 50GHz is achieved. A 40Gbit/s eye-diagram
is successfully observed. The device has a potentiality fur future 100Gbit
/s transmission.
