An optoelectronic component includes an active zone that generates electromagnetic radiation, wherein the electromagnetic radiation is guided in a guide plane, the electromagnetic radiation is output essentially in the guide plane, the active zone emits stray radiation laterally with respect to the guide plane, an electrical contact pad is provided, the contact pad is arranged outside the guide plane, the contact pad is formed by a surface at least partially covered by a conductive layer, the surface has inclined partial faces, and the electrically conductive layer on at least a subset of the inclined faces of the contact pad is configured to be so thin that electromagnetic stray radiation is emitted via the subset of the inclined faces.

Optoelectronic component having stray radiation

A method for producing an optoelectronic component comprising the steps of providing a semiconductor layer sequence having at least one active region, wherein the active region is suitable for emitting electromagnetic radiation during operation, and applying at least one layer on a first surface of the semiconductor layer sequence by means of an ion assisted application method.

Method for producing an optoelectronic component, and an optoelectronic component

A method for fabricating at least one mesa or ridge structure in a layer or layer sequence, in which a sacrificial layer () is applied and patterned above the layer or layer sequence. A mask layer is applied and patterned above the sacrificial layer for definition of the mesa or ridge dimensions. The sacrificial layer () and of the layer or layer sequence are removed so that the mesa or ridge structure is formed in the layer or layer sequence. A part of the sacrificial layer () is selectively removed from the side areas thereof which have been uncovered in the previous step, so that a sacrificial layer remains which is narrower in comparison with a layer that has remained above the sacrificial layer as seen from the layer or layer sequence. A coating is applied at least to the sidewalls of the structure produced in the previous steps so that the side areas of the residual sacrificial layer are not completely overformed by the coating material. The sacrificial layer () is removed so that the layer that has remained above the sacrificial layer as seen from the layer or layer sequence is lifted off. A method is also disclosed for fabricating at least one gain-controlled laser diode in a layer sequence, in which method steps analogous to those described above are employed.
