Abstract
A novel tunable 1550-nm buried heterostructure (BH-) distributed feedback (DFB)-laser is presented consisting of a phase tuning section, a short cavity complex coupled DFB section, and an amplifier section with integrated optical taper. The device shows a narrow optical far-field, a high optical output power, up to 10-Gb/s direct modulation capability and a wavelength tuning range of several nanometers by varying the current in the phase section only.
