OPTICAL SEMICONDUCTOR ELEMENT

摘要

An optical semiconductor element includes a first nitride semiconductor layer of a first conductivity type, a second nitride semiconductor layer of a second conductivity type, and an active layer provided between the first nitride semiconductor layer and the second nitride semiconductor layer. In the optical semiconductor element, a feature is provided in the active layer, and the second nitride semiconductor layer is provided within the feature of the active layer.
