| 英文摘要 | PURPOSE:To obtain a frequency stabilized light source characterized by a low cost, a broad variable wavelength region and high performance, by using a holographic diffraction grating, and arranging the direction of the grooves of the holographic diffraction grating and the P-N junction plane of a semiconductor laser device in parallel. CONSTITUTION:The direction of the grooves of a holographic diffraction grating 4 is arranged in parallel with a P-N junction plane of a semiconductor laser device Light, which is dispersed through the holographic diffraction grating 4, is aligned in the vertical direction with respect to the P-N junction plane of the semiconductor laser device The light in the secondary mode, whose oscillation is to be suppressed, is separated from the active layer of the semiconductor laser. Therefore, the separation of the light 22 in each secondary mode at the end surface of the semiconductor laser becomes good. Unnecessary light is not coupled into the active layer 23 of the semiconductor laser and a light guide part. Thus an intense coupling efficiency of the light in the main mode with the semiconductor laser device 1 is obtained. Oscillation is stabilized and the frequency can be changed in a broad range. |
