| 英文摘要 | A superluminescent diode has an active layer confined in a channel cut into current blocking layers on a semiconductor substrate. This structure gives a small output beam diameter and high coupling efficiency, even when coupled into single-mode fiber. At the end of the channel distant from the output facet, the active layer makes slanting contact with a rough diffusing surface formed by the current blocking layers and substrate. This easily-manufactured diffusing surface reduces optical gain within the active layer, thereby preventing lasing without requiring an antireflection coating. |
