1. A method for sorting optoelectronic semiconductor components each comprising an active region for emission or detection of electromagnetic radiation, comprising the following steps:
introducing the semiconductor components into a sorting region on a specified path,
irradiating the optoelectronic semiconductor components with electromagnetic radiation of a first wavelength range to generate dipole moments by charge separation in the active regions of the optoelectronic semiconductor components, and
deflecting the optoelectronic semiconductor components from the specified path as a function of their dipole moment by means of a non-homogeneous electromagnetic field.
