Abstract (in Japanese) (See Japanese page) 
(in English) We have developed 1.3-um electroabsorption modulator integrated with DFB laser for middle- and long-distance 100 Gbit/s Ethernet. To ensure enough extinction ratio at 1.3-um band, tensile strained quantum well absorbing layer made with InGaAlAs-based material which has larger conduction band offset compared with that of InGaAsP. Butt-joint technique is employed to couple EA modulator and DFB laser in order to optimize the structure separately. Fabricated device is packaged to a butterfly module and the small-signal 3 dB bandwdth is 33 GHz. By using the module, we demonstrate 10- and 40-km transmission on single mode fiber at the modulation speed of 25 Gbit/s at 40 degrees Celcius.
