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. |
其他摘要 | 表面发射激光器元件包括p侧间隔层(106);n侧间隔层(104);以及设置在p侧间隔层(106)和n侧间隔层(104)之间的有源层(105)。p侧间隔层(106)包括与有源层(105)相邻的未掺杂区域,其中不包含p型掺杂剂。整个n侧间隔层(104)掺杂有n型掺杂剂。 |
