Patent ID: 6859478

Claim:
A semiconductor light emitting device comprising: a layered structure including, a substrate, a lower cladding layer of a first conductive type, formed above said substrate, an active zone including an active layer and being formed above said lower cladding layer so as to leave at least one space between at least one near-edge region of said active layer and at least one end facet, an upper cladding layer of a second conductive type, formed above said active zone, and a current confinement layer being formed above said upper cladding layer and having a groove for realizing a current injection window; and a regrowth layer doped with a dopant which makes the regrowth layer said second conductive type; wherein a groove having a depth corresponding to a bottom of said current confinement layer or a lower elevation is formed in said layered structure for realizing a current injection window, said regrowth layer is formed over said layered structure so that said groove and said at least one space are filled with said regrowth layer, and said dopant is diffused into said at least one near-edge region of said active layer adjacent to said at least one space.
