摘要： The invention includes: a mode-locked semiconductor laser having at least a light amplification region 12, a saturable absorbing region 11, a resonator length adjusting region 14, and an optical modulation region 13 for forcedly modulating a light intensity externally in such a configuration that when a reverse bias voltage is applied to the saturable absorbing region and a current is injected to the light amplification region, passive mode-locking occurs, and a natural oscillation is adjusted according to a bias applied to the resonator length adjusting region; an oscillator 15 for applying a sine wave having a reference frequency to the optical modulation region to thereby carry out forced optical modulation; a photo-detector 30 for photo-electrically converting an output light of the mode-locked semiconductor laser into an electric signal; a driving device 34 for supplying a bias to the resonator length adjusting region; a noise detecting device 32 for receiving an output of the photo-detector as an input to thereby extract a low-frequency noise component; and a control device 33 for adjusting a bias for the resonator length adjusting region by controlling the driving device so as to minimize the intensity of the noise component.

摘要： In an external-cavity tunable wavelength light source using a semiconductor laser (LD), an oscillation wavelength is tuned by simultaneously changing a current to be injected to the phase adjustment area of the LD and the rotation angle of a diffraction grating while holding the same external cavity longitudinal mode. A light beam emitted from the AR-coated end face of the LD (6) having the phase adjustment area (6b) is collimated by a lens (2) and incident on the diffraction grating (3). Only a light component having a specific wavelength selected upon spectral dispersion is reflected by the diffraction grating (3) and returns to the LD (6). With this operation, an external cavity (effective cavity length K) is formed between the LD (6) and the diffraction grating (3), thereby performing laser oscillation at a wavelength determined by an external cavity longitudinal mode and the cavity loss of the diffraction grating (3). The effective cavity length K can be changed in accordance with the current to be injected to the phase adjustment area (6b). A current injection unit (7) injects the current to the phase adjustment area. An oscillation wavelength control unit (8) controls the injection current output from the current injection unit (7) and the rotation angle of the diffraction grating (3).
