    摘要: A nitride semiconductor light-emitting device has a semiconductor ridge, and includes a first inner-layer between an active layer and an n-type cladding and a second inner-semiconductor layer between the active layer and a p-type cladding. The first inner-layer, active layer and second inner-layer constitute a core-region. The n-type cladding, core-region and p-type cladding constitute a waveguide-structure. The active layer and the first inner-layer constitute a first heterojunction inclined at an angle greater than zero with respect to a reference plane of the c-plane of the nitride semiconductor of the n-type cladding. Piezoelectric polarization of the well layer is oriented in a direction from the p-type cladding toward the n-type cladding. The second inner-layer and InGaN well layer constitute a second heterojunction. A distance between the ridge bottom and the second heterojunction is 200 nm or less. The ridge includes a third heterojunction between the second inner-layer and the p-type cladding.

    摘要: A monolithically integrated laser diode chip having a construction as a multiple beam laser diode, which, on a semiconductor substrate (3) comprised of GaAs, has at least two laser stacks (4a, 4b, 4c) which are arranged one above another and which each contain an active zone (7). The active zone (7) is in each case arranged between waveguide layers (8). The waveguide layers (8) each adjoin a cladding layer (6) at a side remote from the active zone. At least one of the waveguide layers (8) or cladding layers (6) of at least one laser stack (4a, 4b, 4c), comprises AlxGa1-xAs, where 0≦x≦1, and at least one additional material from main group III or V, such that the lattice mismatch between the at least one waveguide layer (8) or cladding layer (6) comprising the at least one additional element and the semiconductor substrate (3) composed of GaAs is reduced. This increases the lifetime of the laser diode chip.
