SEMICONDUCTOR LIGHT EMITTING ELEMENT

摘要

A semiconductor light-emitting element includes a multilayer body including a first end surface and a second end surface which are opposed to each other, wherein a first semiconductor layer, a light emitting layer, and a second semiconductor layer are stacked; a pair of recesses that are formed on the second semiconductor layer, separated from the second end surface, and separated from each other in the direction parallel to the first and second end surfaces; a ridge portion that is a protrusion between the pair of recesses and extends along the direction perpendicular to the first and second end surfaces; a band-shaped electrode disposed on the ridge portion; and a light guide layer formed on the second semiconductor layer between the ridge portion and the second end surface and guides light from the light emitting layer.

1. A semiconductor light-emitting element comprising:
a semiconductor multilayer body having a first end surface and a second end surface which are opposed to each other, wherein a first semiconductor layer, a light emitting layer, and a second semiconductor layer which is an opposite conductivity-type to that of the first semiconductor layer are stacked, in this order, on a substrate; a pair of recesses that are formed on the second semiconductor layer, separated from the second end surface, and separated from each other in a direction parallel to the first end surface and the second end surface; a ridge portion that is a protrusion between the pair of recesses and extends along a direction perpendicular to the first end surface and the second end surface; a band-shaped electrode disposed on the ridge portion; and a light guide layer that is formed on the second semiconductor layer between the ridge portion and the second end surface and guides radiation light, from the light emitting layer.
