| 英文摘要 | A semiconductor laser device, including a substrate; a ridge stripe formed on the substrate and including an active layer, an n-cladding layer and p-cladding layer, the n-cladding layer and the p-cladding layer interposing the active layer; in which the ridge stripe has a laser unit which lases. In one embodiment the ridge stripe has a tip portion having a tapered shape, and an angle formed inside the ridge stripe by a bottom surface of the ridge stripe and a side surface of the ridge stripe is in the range of about 60° and about 90°. In one embodiment, the laser device includes a misoriented substrate and the ridge stripe has current blocking layers formed on both sides thereof. |
