  • Semiconductor laser cladding layers
    Publication number: 20040223529
    Abstract: Cladding layers for semiconductor lasers provide improved heat transfer and optical confinement properties. The cladding layers may comprise superlattices such as AlSb/GaAs, AlSb/AlAs, AlSb/GaSb/AlAs, AlGaSb/AlGaAs and AlSb/AlGaAs. The cladding layers may also comprise Al-As-Sb ternary alloys or Al-Ga-As-Sb quaternary alloys. Such cladding layers may be used in interband cascade lasers or other types of semiconductor lasers to significantly increase heat flow out of the active light-emitting region of the device, while providing improved optical confinement characteristics.
