Abstract:
1. A semiconductor light-emitting element comprising: a first Group III-V compound semiconductor; a current confining layer, which is made of a second Group III-V compound semiconductor that has grown on a selected surface area of the first Group III-V compound semiconductor and which has a striped opening extending along the length of a resonant cavity; and a third Group III-V compound semiconductor, which covers the surface of the first Group III-V compound semiconductor that is exposed through the striped opening and the surface of the current confining layer, wherein the current confining layer has two overhanging portions that overhang toward the striped opening, each of the two overhanging portions being made of a laterally grown layer, a first gap is provided between each of the two overhanging portions of the current confining layer and a part of the surface of the first Group III-V compound semiconductor, the first gap not being filled by the third Group III-V compound semiconductor, and wherein a second gap between the two overhanging portions facing each other is defined as W
