| 英文摘要 | The pulse laser light source apparatus in the OTDR apparatus of present invention comprises an optical waveguide which receives and guides the light emitted from the first light-emitting end face, wherein the optical waveguide comprises a reflecting area which selectively reflects a part of light emitted from a light-emitting end face of a semiconductor light-emitting device, a core of the reflecting area comprises a first diffraction grating which is disposed in a first area and whose refractive index periodically changes along an optical-axis direction, the first diffraction grating selectively reflects, of the light emitted from the light-emitting end face of the semiconductor light-emitting device, a part of the light within a first wavelength range. And the diffraction grating is one of denvices which constitute a laser resonator. |
