Abstract
Device and tuning characteristics of sampled grating tunable twin-guide laser diodes are presented. The vertically integrated, monolithic widely tunable laser requires only two tuning currents to fully cover a wavelength range of more than 40 nm by electrooptic tuning. Its tuning behavior is quasi-continuous with up to 8.2-nm broad continuous tuning regions. High sidemode suppression (SMSR ≥ 35 dB) as well as large output power (P ≥ 10 mW) are obtained over the wavelength range from 1520.5 to 1561.5 nm.
