| 英文摘要 | An external cavity type wavelength-tunable light source including an optical amplifier on one end surface of which an antireflection film is coated, a diffraction grating arranged on an emission light axis of the optical amplifier on the side of the antireflection film and having wavelength selectivity, a reflector arranged on a reflection light axis of the diffraction grating, for reflecting a reflection light beam from the diffraction grating, and a wavelength tuning mechanism for tuning a wavelength of an lasing light beam by changing an angle of the reflector relative to the reflection light axis of the diffraction grating. The wavelength tuning mechanism includes a bimorph type piezo-electric element as a wavelength-tunable controlling unit for changing an angle of the reflector relative to the reflection light axis of the diffraction grating, and a wavelength-tunable driving circuit for controlling a voltage applied to the bimorph type piezo- electric element to tune the wavelength of the lasing light beam. |
