Patent ID: 8000366

Claim:
A semiconductor laser structure, comprising: a gallium nitride (GaN) template layer; a lower cladding layer formed over said gallium nitride (GaN) template layer, said lower cladding layer comprising at least aluminum gallium indium nitride (AlGaInN); an active layer comprised of gallium indium nitride (GaInN) formed over said lower cladding layer; and an upper cladding layer comprising at least aluminum gallium indium nitride (AlGaInN); whereby the active layer is substantially lattice matched to the lower cladding layer; and wherein at least one of said lower and said upper cladding layers comprise aluminum indium nitride substantially in the ratio of Al 0.74 In 0.26 N, and said active layer comprises a plurality of quantum well sublayers each comprising gallium indium nitride substantially in the ratio of Ga 0.73 In 0.27 N, each quantum well sublayer separated from another by a barrier sublayer comprising resin gallium indium nitride substantially in the ratio of Ga 0.88 In 0.12 N.
