Abstract
The present invention is directed to a semiconductor laser device comprising a first resonator section for resonating an optical resonator signal for providing an optical output signal at an output of said laser device, wherein said first resonator section is arranged for selectively resonating at a plurality of discrete output wavelengths, and wherein said laser device further comprises a second resonator section operatively connected to said first resonator section, said second resonator section being arranged for providing an optical feedback signal at a feedback wavelength to said first resonator section for locking said first resonator section into resonating at a selected output wavelength of said discrete output wavelengths, which selected output wavelength corresponds to said feedback wavelength for providing said optical output signal.
