摘要： A processing unit (12) reads out, from a memory (10), wavelength setting data corresponding to wavelength information from a key input section (9), and outputs a wavelength setting command corresponding to the wavelength setting data to a tunable-wavelength control section (13) and a spectral wavelength control section (14). The tunable-wavelength control section (13) controls a tunable-wavelength light source section (1) to output a laser beam having a wavelength corresponding to the wavelength setting data. The spectral wavelength control section (14) controls a spectroscope section (6) to perform spectroscopy of the light having the wavelength corresponding to the wavelength setting data and output the resultant light. Output light from the tunable-wavelength light source section (1) whose wavelength has been set is input to an object (15) to be measured. Light passing through the object (15) is input to the spectroscope section (6). The spectroscope section (6) performs spectroscopy of only the light having the wavelength corresponding to the wavelength setting data. A light-receiving section (7) receives the spectral light and photoelectrically converts it. The resultant light is converted into digital data by an A/D conversion section (8) to be input as level data to a processing unit (12). The processing unit (12) obtains a light-reception level on the basis of the digital level data.

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).
