| Abstract(in English) | We report on a recent progress in 1.3 μm InAs/GaAs high-density quantum dot lasers. By stacking high-density quantum dot layer where areal density is 5.9×10^<10>cm^<-2> by molecular beam epitaxy we have successfully increased the optical modal gain beyond 40 cm^<-1>. The fabricated Fabry Perot laser showed an extended modulation bandwidth to 11 GHz, and 25 Gb/s eye-diagram which was the first demonstration in quantum dot lasers, to the best of our knowledge. We also fabricated distributed feedback lasers with eight-layer-stacked high-density quantum dot as an active layer, in which InGaP/GaAs gratings were formed just above the active layer. Excellent single mode lasing and temperature stable 10.3 Gb/s modulation characteristics have been achieved in the temperature range between -40℃ and 80℃. |
