| 英文摘要 | A surface emitting laser element includes a p-side spacer layer (106); an n-side spacer layer (104); and an active layer (105) disposed between the p-side spacer layer (106) and the n-side spacer layer (104). The p-side spacer layer (106) includes an undoped region adjacent to the active layer (105) in which no p-type dopant is contained. The entire n-side spacer layer (104) is doped with an n-type dopant. |
