Abstract
We present transmission beyond the dispersion limit with a blue-chirp modulator integrated DFB laser for the first time. By suppressing the hole pile-up in the modulator, stable modulation characteristics were realized in negative /spl alpha/ regime. Blue-chirp operation was clearly observed by time-resolved dynamic chirp measurement. Penalty-free 10 Gb/s transmission over 100 km of standard fiber at 1.55 /spl mu/m was demonstrated with the device. This modulator integrated DFB laser is promising for use as a high-power blue-chirp transmitter in multigigabit transmission systems.Keywords
