英文摘要	A wavelength-tunable laser device has an active part comprising an active laser region for generating a laser emission with a predetermined emission wavelength, and a tuning part comprising a tuning region allocated to the active laser region and capable of tuning the emission wavelength of the laser light emitted by the active region. The active part is charged with a chronologically variable modulation current that controls the intensity of the emitted laser emission, and the tuning part is charged with an electrical tuning current for controlling the emission wavelength of the emitted laser light. The active part controls the intensity of the emitted laser light and the tuning part is charged with an electrical tuning current for controlling the emission wavelength of the emitted laser light. The tuning current that is supplied to the tuning part and controls the emission wavelength of the emitted laser light is directly derived from the chronologically variable modulation current. Further, the tuning current directly derived from the chronologically variable modulation current controls the tuning region acting on the active laser region such that the emission wavelength of the emitted laser light is kept independent of the intensity of the modulation current, and is kept essentially at least approximately to a constant value.
