Fabrication and Characteristics of Tunable Twin-Guide DFB Lasers by All MOVPE,
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.
