| 英文摘要 | PURPOSE:To narrow a width of oscillating spectrum while stabilizing a frequency, by providing a grating waveguide adapted such that one end thereof is connected to one end of an optical waveguide. CONSTITUTION:Light emitted by a laser light generating means 1 is guided through an optical waveguide 15 formed on a ferro-electric substrate 14 and reaches a grating waveguide 16. Only the light rays having a wavelength selected by filtering function of the grating waveguide 16 are reflected, travel back through the optical waveguide 15 and are emitted from the laser light generating means Selection of wavelengths of the reflected return rays 9 in the grating waveguide 16 as well as an effective wavelength of the light ray from the light-emitting end face of the laser light generating means 1 to the grating waveguide 16 can be controlled electrically. Thus, it is possible to obtain an extremely stable light rays with narrow spectrum. Further, since only light rays having a particular wavelength are fed back by the grating waveguide, a frequency at the spectrum center can be stabilized. |
