Abstract:
1. A semiconductor light emitting device composed of a Group III nitride semiconductor, comprising: a substrate; a first conductivity-type first semiconductor layer provided above the substrate; an active layer provided over the first semiconductor layer; a second conductivity-type second semiconductor layer provided over the active layer; two first end faces formed by cleavage and opposite each other in planar view; two trenches extending to the two first end faces in a direction orthogonal to the first end faces in planar view, wherein bottoms of the trenches are positioned at least below a lower surface of the active layer; and second end faces formed in the direction orthogonal to the first end faces and outside the trenches, the second end faces being formed by laser scribing, wherein the first semis conductor layer comprises: the active layer has a multiple quantum well structure, the second semiconductor layer comprises: wherein the bottoms of the trenches are positioned in the first cladding layer.
