| 英文摘要 | It is possible to narrow the emission spectrum linewidth of a semiconductor laser device by coupling optically an external resonator (2) with one end surface of the semiconductor laser (l). However, the structure of the external resonator (2) should match the phase of the light emitted by the laser (l). Heretofore, this matching has been effected by adjusting the length of the external resonator (2), and hence productivity and reproducibility have not been good. According to this invention, characteristics of the external resonator (2) can be adjusted electrically to be matched with the phase of the emitted light owing to the fact that the external resonator (2) is made of a material, whose refractive index can be varied electrically. Therefore the semiconductor laser device according to this invention is very practical. |
