Abstract
A method of producing a radiation-emitting component is provided. A far field radiation pattern is predetermined. From the predetermined radiation pattern a refractive index profile for the radiation-emitting component is determined in a direction extending perpendicularly to a main emission direction of the component. A structure is determined for the component, such that the component includes the previously determined refractive index profile. The component is configured according to the previously determined structure.
Claims18
A radiation-emitting component comprising:
- an active region provided for producing radiation, the component having a main emission direction;
- and
- field-shaping layers arranged on each side of the active region and a refractive index profile being formed perpendicular to the main emission direction of radiation by means of the field-shaping layers, the refractive index profile comprising an abrupt junction on each side of the active region, wherein the refractive index profile at each junction increases from the standpoint of the active region,
- wherein one of the field-shaping layer comprises a sub-region and a further sub-region, a refractive index in the sub-region and the further sub-region reducing as the distance from the active region increases, wherein the sub-region and the further sub-region are arranged on a same side of the active region.
