英文摘要 | The invention relates to a radiation-emitting semiconductor index-guided diode, especially a laser having a first (1) and a second (3) cladding layer, an active layer (2) and a mesa (20) which comprises at least the second cladding layer (3) and which lies recessed in a third cladding layer (4). In a diode according to the invention, the second cladding layer (3) comprises a first sub-layer (3A) which adjoints the active layer (2) and is comparatively thin, and a second sub-layer (3B) which adjoins the first sub-layer (3A) and is comparatively thick, while the refractive index of the first sub-layer (3A) is lower than that of the second sub-layer (3B). On the one hand the confinement in the thickness direction of charge carriers and radiation is good in such a diode. On the other hand, the third cladding layer (4) is allowed to have a comparatively high refractive index, so a comparatively low bandgap, and thus a comparatively low aluminium content, while nevertheless the lateral confinement of the radiation is good. Thus, the aluminium content of the third cladding layer (4) may be below 50 at.% or below 40 at.% in GaAs/AlGaAs or InGaAs/AlGaAs diodes, respectively, which cover the important wavelength range from 0.7 to 1 mu m. |
