    摘要: The semiconductor laser device includes an active layer, a p-type cladding layer, and a p-type cap layer. The layers are sequentially stacked so that the semiconductor laser device is provided. The p-type cap layer includes both a p-type dopant and an n-type dopant. In another aspect, the p-type cap layer includes a first layer including a first p-type dopant and a second layer including a second p-type dopant having a diffusion coefficient smaller than that of the first p-type dopant. The first layer is far from the active layer, and the second layer is close to the active layer. In further aspect, the p-type cap layer includes carbon (C) as a p-type dopant. According to these configuration, the p-type dopant can be prevented from being diffused in the active layer and the p-type cladding layer.

    摘要: A first buffer layer (GaAs), a second buffer layer (AlGaAs), and a diffusion suppressing layer consisting of GaAs or AlGaAs are stacked on a GaAs substrate. The structure has a first clad layer formed thereon. When AlGaAs is used for the diffusion suppressing layer, the Al ratio of AlGaAs is made smaller than the second buffer layer. By such a structure, when the window layer is formed, the diffusion rate of the impurity (Zn) can be lowered in the diffusion suppressing layer, and the diffusion of the impurity can be stopped at the second buffer layer.

The structure has a first cladding layer thereon. When AlGaAs is used for the diffusion suppressing layer, the Al ratio of AlGaAs is made smaller than in the second buffer layer. In such a structure, when a window region is formed, the diffusion rate of the impurity (Zn) can be lowered in the diffusion suppressing layer, and the diffusion of the impurity can be stopped at the second buffer layer.
