Abstract : Wavelength tunable lasers are expected to be used as the key devices for coherent optical transmission systems. Continuous tuning range of 7nm has been reported in tunable twin-guide (TTG) laser) and we have reported 2.6nm continuous tuning range in TTG laser fabricated by all MOVPE2. Here, we report on the tuning characteristics of the TTG-DFB lasers fabricated by an improved process. The TTG-DFB lasers were fixed by 9-fold MOVPE. The threshold current was 16mA, and the continuous tuning range exceeded 5.3nm.
