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:
A method for fabricating an infrared-emitting light-emitting diode in which a layer sequence is applied onto a semiconductor substrate, preferably composed of GaAs. The layer sequence has, proceeding from the semiconductor substrate, a first AlGaAs cover layer, a GaAs and/or AlGaAs containing active layer and a second AlGaAs cover layer. In which case, the first AlGaAs cover layer and the active layer are fabricated by a metal organic vapor phase epitaxy (MOVPE) method and the second AlGaAs cover layer is fabricated by a liquid phase epitaxy (LPE) method. Furthermore, an electrically conductive coupling-out layer having a thickness of at least about 10 &mgr;m is deposited on the second AlGaAs cover layer by the LPE method. The coupling-out layer is optically transparent in the infrared spectral region.

An optoelectronic component contains a semiconductor chip (1) and a carrier body (10), which are provided with a transparent, electrically insulating encapsulation layer (3), the encapsulation layer (3) having two cutouts (11, 12) for uncovering a contact area (6) and a connection region (8) of the carrier body, and an electrically conductive layer (14) being led from the contact area (6) over a partial region of the encapsulation layer (3) to the electrical connection region (8) of the carrier body (10) in order to electrically connect the contact area (6) and the electrical connection region (8) to one another. The radiation emitted in a main radiation direction (13) by the semiconductor chip (1) is coupled out through the encapsulation layer (3), which advantageously contains luminescence conversion substances for the wavelength conversion of the emitted radiation.

摘要:
An optoelectronic component includes a carrier element. At least two elements are arranged in an adjacent fashion on a first side of the carrier element. Each element has at least one optically active region for generating the electromagnetic radiation. The optoelectronic component has an electrically insulating protective layer arranged at least in part on a surface of the at least two adjacent elements which lies opposite the first side. The protective layer, at least in a first region arranged between the at least two adjacent elements, at least predominantly prevents a transmission of the electromagnetic radiation generated by the optically active regions.
