INTEGRATED SEMICONDUCTOR LASER ELEMENT AND SEMICONDUCTOR LASER MODULE |
摘要 |
An integrated semiconductor laser element which is obtained by integrating, on a substrate, a semiconductor laser and a semiconductor optical amplifier that amplifies output laser light of the semiconductor laser, and which is characterized in that: the semiconductor laser comprises a first active layer; the semiconductor optical amplifier comprises a second active layer; the first active layer and the second active layer have a multiple quantum well structure; and the second active layer has more number of quantum wells than the first active layer. Consequently, there can be achieved: an integrated semiconductor laser element which has output laser light having a narrow spectral line width and a high intensity; and a semiconductor laser module. |
