F. Kano et al., CHARACTERISTICS OF SUPERSTRUCTURE GRATING (SSG) DBR LASERS UNDER BROAD RANGE WAVELENGTH TUNING, IEEE photonics technology letters, 5(6), 1993, pp. 611-613
Spectral characteristics of the super structure grating (SSG) DBR lase
rs are studied under broad range wavelength tuning. SSG DBR lasers sho
w good spectral characteristics with broad range wavelength tunability
. Under the directly intensity modulated condition, stable single long
itudinal mode oscillations are also obtained over the broad wavelength
tuning range.
