    摘要: A radiation emitter component, in particular an infrared emitter component with a conventional light-emitting diode housing, includes two electrode connections, one of which has a well-shaped reflector. The housing has an optically transparent, electrically non-conducting encapsulation material. A semiconductor laser chip is fastened in a well-shaped reflector of the light-emitting diode housing. The semiconductor laser chip has a quantum well structure, in particular with a strained layer structure, for example MOVPE epitaxial layers with a layer sequence GaAlAs-InGaAs-GaAlAs. A diffusor material can be inserted into the optically transparent, electrically non-conducting material of the light-emitting diode housing. The diffusor material is constructed or inserted with regard to type and concentration in such a way that in connection with the semiconductor laser chip encapsulated in the light-emitting diode housing, a radiation characteristic curve or an increase of an effective emission surface is produced that is comparable to that of a conventional infrared light-emitting diode.

    摘要: An edge emitting semiconductor laser containing a plurality of monolithically integrated laser diodes (1, 2, 3). Each laser diode (1, 2, 3) contains an active zone (11, 12, 13), with the active zones (11, 12, 13) being in each case arranged between waveguide layers (6), the waveguide layers (6) in each case adjoining a cladding layer (7, 8) at a side remote from the active zone (11, 12, 13). The cladding layers (7, 8) comprise inner cladding layers (7), which are arranged above a bottommost active zone (11) and below a topmost active zone (13), and outer cladding layers (8) which are arranged below the bottommost active zone (11) or above the topmost active zone (13). The inner cladding layers (7) have a smaller thickness than the outer cladding layers (8).
