Abstract
The radiation emitting optoelectronic component has a radiation generating body with a planar optical waveguide and a wave guiding layer. The wave guiding layer has a radiation generating zone in which electromagnetic radiation is generated while the component is operating. The planar optical waveguide has at least one lateral output taper for outputting the radiation from the waveguide.

An incoherent radiation-emitting optoelectronic component, comprising:
- a radiation generating body formed with a planar optical waveguide having a wave guiding layer arranged between two reflecting layers, said planar optical waveguide defining a direction of wave propagation;
- a radiation generating zone formed in said wave guiding layer for generating electromagnetic radiation;
- a device formed in said radiation generating body for lateral current pinching in said radiation generating body;
- and
- said wave guiding layer having an outer side face enclosing a given angle with the direction of wave propagation in said planar optical waveguide.
