    Abstract: The invention relates to an infrared emitter component with a commercial light-emitting diode (LED) package (11) which has two electrode terminals (13, 14), one of which has a well-shaped reflector (12), and which has an optically transparent, electrically nonconductive encapsulating material (16). The invention provides that a semiconductor laser chip (1) is mounted in the well-shaped reflector (12) of the LED package. The semiconductor laser chip (1) has a quantum-well structure, especially with a strained-layer structure, for example MOVPE epitaxial layers with the layer sequence GaAlAs-InGaAs-GaAlAs. The optically transparent, electrically nonconductive material (16) of the LED package (11) may incorporate a diffuser material (17) which in terms of type and concentration is structured and introduced so as to produce, in conjunction with the semiconductor laser chip (1) encapsulated in the LED package (11), a radiation characteristic or an enlargement of the effective emission surface that is comparable to that of a commercial infrared LED.

    Abstract: A process is disclosed for manufacturing an infrared-emitting luminescent diode. A series of layers is applied on a semiconductor substrate (1) preferably made of GaAs. Counting from the semiconductor substrate (1), the series of layers comprises a first AlGaAs covering layer (2), an active layer (3) containing GaAs and/or AlGaAs and a second AlGaAs covering layer (4). The first AlGaAs covering layer (2) and the active layer (3) are produced by an MOVPE (metallo-organic vapour phase epitaxy) process and the second AlGaAs covering layer (4) is produced by an LPE (liquid phase epitaxy) process. In addition, an electroconductive decoupling layer (5) which is optically transparent in the infrared spectral range and has at least about 10 mu m thickness is deposited on the second AlGaAs covering layer (4) by an LPE (liquid phase epitaxy) process.
